xes, etc. to wherever you happen to be at the moment. Avi, for example, uses it all the time. Scrolling down, Randy finds: Record last updated on 18 Nov 98. Record created on 1 Mar 90. The "90" jumps out. That's a prehistoric date by Internet standards. It means that Societas Eruditorum was way ahead of the game. Especially for a group based in Leipzig, which was part of East Germany until about then. Domain servers in listed order: NS.SF.LAUNDRY.ORG followed by the dotted quad for laundry.org, which is a packet anonymizer used by many Secret Admirers to render their communications untraceable. It all adds up to nothing, yet Randy can't get away with assuming that this message came from a bored sixteen year old. He should probably make some token response. But he's afraid that it'll turn out to be a come on for some kind of business proposition: probably some mangy high tech company that's looking for capital. In the latest version of the business plan, there is probably some explanation of why Epiphyte(2) is building the Crypt. Randy can simply cut and paste it into an e mail reply to root@pallas.eruditorum.org. It'll be something vaporous and shareholder pleasing, and therefore kind of alienating. With any luck it will discourage this person from pestering him anymore. Randy double clicks on Ordo's eyeball/pyramid icon, and it opens up a little text window on the screen, where he is invited to type commands. Ordo's also got a lovely graphical user interface, but Randy scorns it. No menus or buttons for him. He types >decrypt epiphyteBizPlan.5.4.ordo The computer responds verify your identity: enter the pass phrase or 'bio' to opt for biometric verification. Before Ordo will decrypt the file, it needs to have the private key: all 4096 bits of it. The key is stored on Randy's hard disk. But bad guys can break into hotel rooms and read the contents of hard disks, so the key itself has been encrypted. In order to decrypt it, Ordo needs the key to the key, which (in Cantrell's one concession to user friendliness) is a pass phrase: a string of words, easier to remember than 4096 binary digits. But it has to be a long phrase or else it's too easy to break. The last time Randy changed his pass phrase, he was reading another World War II memoir. He types: >with hoarse shouts of "banzai!" the drunken Nips swarmed out of their trenches, their swords and bayonets flashing in the beams of our searchlights and hits the "return" key. Ordo responds: incorrect pass phrase reenter the pass phrase or "bio" to use biometric verification. Randy curses and tries it a few more times, with slight changes in punctuation. Nothing works. In desperation and out of curiosity, he tries: bio and the software responds: unable to locate biometric configuration file. Talk to Cantrell : / Which is of course not a normal part of the software. Ordo does not come with biometric verification, nor do its error messages refer to John Cantrell, or anyone else, by name. Cantrell has apparently written a plug in module, a little add on, and distributed it to his friends in Epiphyte(2). "Fine," Randy says, picks up his phone, and dials John Cantrell's room number. This being a brand new, modern hotel, he gets a voice mail box in which John has actually bothered to record an informative greeting. "This is John Cantrell of Novus Ordo Seclorum and Epiphyte Corporations. For those of you who have reached me using my universal phone number and consequently have no idea where I am: I am in the Hotel Foote Mansion in the Sultanate of Kinakuta please consult a quality atlas. It is four o'clock in the afternoon, Thursday March twenty first. I'm probably down in the Bomb and Grapnel." *** The Bomb and Grapnel is the pirate themed hotel bar, which is not as cheesy as it sounds. It is decorated with (among other museum grade memorabilia) several brass cannons that seem authentic. John Cantrell is seated at a corner table, looking as at home here as a man in a black cowboy hat possibly can. His laptop is open on the table next to a rum drink that has been served up in a soup tureen. A two foot long straw connects it to Cantrell's mouth. He sucks and types. Watching incredulously is a cadre of tough looking Chinese businessmen sitting at the bar; when they see Randy coming in, carrying his own laptop, they buzz up. Now there's two of them! Cantrell looks up and grins something he cannot do without looking fiendish. He and Randy shake hands triumphantly. Even though they've only been riding around on 747s, they feel like Stanley and Livingstone. "Nice tan," Cantrell says puckishly, all but twirling his mustache. Randy's caught off guard, starts and stops talking twice, finally shakes his head in defeat. Both men laugh. "I got the tan on boats," Randy says, "not by the hotel pool. The last couple of weeks, I've been putting out fires all over the place." "Nothing that'll impact shareholder value, I hope," Cantrell deadpans. Randy says, "You're looking encouragingly pale." "Everything's fine on my end," Cantrell says. "It's like I predicted lots of Secret Admirers want to work on a real data haven." Randy orders a Guinness and says, "You also predicted that a lot of those people would turn out to be squirrelly and undisciplined." "Didn't hire those," Cantrell says. "And with Eb to handle the weird stuff, we've been able to roll right over the few speed bumps we've encountered." "Have you seen the Crypt?" Cantrell raises an eyebrow and shoots him a flawless imitation of a paranoid glance. "It's like that NORAD command bunker in Colorado Springs," he says. "Yeah!" Randy laughs. "Cheyenne Mountain." "It's too big," Cantrell announces. He knows Randy is thinking the same thing. So Randy decides to play devil's advocate. "But the sultan does everything big. There are big paintings of him in the big airport." Cantrell shakes his head. "The Information Ministry is a serious project. The sultan didn't just make it up. His technocrats conceived it." "I'm told Avi did a little bit of deft turkey baster work ..." "Whatever. But the people behind it, like Mohammed Pragasu, are all Stanford B School types. Oxford and Sorbonne graduates. It's been engineered to the doorstops by Germans. That cave is not a monument to the sultan." "No, it's not a vanity project," Randy agrees, thinking of the chilly machine room that Tom Howard is building a thousand feet below the cloud forest. "So there must be some rational explanation for how big it is." "Maybe it's in the business plan?" ventures Randy. Cantrell shrugs; he hasn't read it either. "The last one I read cover to cover was Plan One. A year ago," admits Randy. "That was a good business plan," Cantrell says. (1) Randy changes the subject. "I forgot my pass phrase. Need to do that biometric thing with you." "It's too noisy here," Cantrell says, "it works by listening to your voice, doing Fourier shit, remembering a few key numbers. We'll do it in my room later." Feeling some need to explain why he hasn't been keeping up with his e mail, Randy says, "I have been totally obsessed, interfacing with these AVCLA people in Manila." "Yup. How's that going?" "Look. My job's pretty simple," Randy says. "There's that big Nipponese cable from Taiwan down to Luzon. A router at each end. Then there's the network of short run, interisland cables that the AVCLA people are laying in the Philippines. Each cable segment begins and ends at a router, as you know. My job is to program the routers, make sure the data will always have a clear path from Taiwan to Kinakuta." Cantrell glances away, worried that he's about to get bored. Randy practically lunges across the table, because he knows it's not boring. "John! You are a major credit card company!" "Okay." Cantrell meets his gaze, slightly unnerved. "You are storing your data in the Kinakuta data haven. You need to download a terabyte of crucial data. You begin the process your encrypted bytes are screaming up through the Philippines at a gigabyte per second, to Taiwan, from there across to the States." Randy pauses and swigs Guinness, building the drama. "Then a ferry capsizes off Cebu." "So?" "So, in the space of ten minutes, a hundred thousand Filipinos all pick up their telephones simultaneously." Cantrell actually whacks his forehead. "Oh, my god!" "Now you understand! I've been configuring this network so that no matter what happens, the data continues to flow to that credit card company. Maybe at a reduced speed but it flows." "Well, I can see how that would keep you busy." "And that's why all I'm really up to speed on is these routers. And incidentally they're good routers, but they just don't have enough capacity to feed a Crypt of that size, or justify it economically." "The gist of Avi and Beryl's explanation," Cantrell says, "is that Epiphyte is no longer the sole carrier into the Crypt." "But we're laying the cable here from Palawan " "The sultan's minions have been out drumming up business," Cantrell says. "Avi and Beryl are being vague, but from comparing notes with Tom, and reading tea leaves, methinks there's one, maybe two other cables coming into Kinakuta." "Wow!" Randy says. It's all he can think of. "Wow!" He drinks about half of his Guinness. "It makes sense. If they're doing it once with us, they can do it again, with other carriers. "They used us as leverage to bring in others," Cantrell says. "Well . . . the question is, then, is the cable through the Philippines still needed? Or wanted?" "Yup," Cantrell says. "It is?" "No. I mean, yup, that's the question, all right." Randy considers it. "Actually, this could be good news for your phase of the operation. More pipes into the Crypt means more business in the long run. Cantrell raises his eyebrows, a little worried about Randy's feelings. Randy leans back in his chair and says, "We've had debates before about whether it makes sense for Epiphyte to be screwing around with cables and routers in the Philippines." Cantrell says, "The business plan has always maintained that it would make economic sense to be running a cable through the Philippines even if there weren't a Crypt at the end of it." "The business plan has to say the Intra Philippines network could be spun off as an independent business, and still survive," Randy says, "to justify our doing it." Neither one of them needs to say any more. They've been concentrating on each other pretty intensely for a while, shutting out the rest of the bar with their postures, and now, spontaneously, both of them lean back, stretch, and begin looking around. The timing's fortuitous, because Goto Furudenendu has just come in with a posse of what Randy guesses are civil engineers: healthy looking, clean cut Nipponese men in their thirties. Randy invites him over with a smile, then flags down their waiter and orders a few of those great big bottles of bitterly cold Nipponese beer. "This reminds me the Secret Admirers are really on my case," Randy says. Cantrell grins, showing some affection for those crazy Secret Admirers. "Smart, rabidly paranoid people are the backbone of cryptology," he says, "but they don't always understand business." "Maybe they understand it too well," Randy says. He is left with some residual annoyance that he came down to the Bomb and Grapnel party in order to answer the question posed by root@eruditorum.org ("Why are you doing it?") and he still doesn't know. As a matter of fact, he knows less now than he did before. Then the men from Goto join them, and it just happens that Eberhard Föhr and Tom Howard show up at just the same time. There is a combinatorial explosion of name card exchanges and introductions. It seems like protocol demands a lot of serious social drinking now Randy's inadvertently challenged these guys' politeness by ordering them beer, and they have to demonstrate that they will not be bested in any such contest. Tables get pushed together and everything gets just unbelievably jovial. Eb has to order some beer for everyone too. Pretty soon things have degenerated into karaoke. Randy gets up and sings "Me and You and a Dog Named Boo." It's a good choice because it's a mellow, laid back song that doesn't demand lots of emoting. Or singing ability, for that matter. At some point Tom Howard puts his beefy arm up on the back of Cantrell's chair, the better to shout into his ear. Their matched Eutropian bracelets, engraved with "Hello Doctor, please freeze me as follows" messages, are glittery and conspicuous, and Randy's nervous that the Nipponese guys are going to notice this and ask questions that will be exceedingly difficult to answer. Tom is reminding Cantrell of something (for some reason they always refer to Cantrell in this way; some people are just made to be called by last names). Cantrell nods and shoots Randy a quick and somewhat furtive look. When Randy looks back at him, Cantrell glances down apologetically and takes to chivvying his beer bottle nervously between his hands. Tom just keeps looking at Randy kind of interestedly. All of this motivated glancing finally brings Randy and Tom and Cantrell together at the farthest end of the bar from the karaoke speakers. "So, you know Andrew Loeb," Cantrell says. It's clear he's basically dismayed by this and yet sort of impressed too, as if he'd just learned that Randy had once beaten a man to death with his bare hands and then just never bothered to mention it. "It's true," Randy says. "As well as anyone can know a guy like that." Cantrell is paying undue diligence to the project of picking the label off of his beer bottle and so Tom picks up the thread now. "You were in business together?" "Not really. Can I ask how you guys are aware of this? I mean, how do you even know that Andrew Loeb exists in the first place? Because of the Digibomber thing?" "Oh, no it was after that. Andy became a figure of note in some of the circles where Tom and I both hang out," Cantrell says. "The only circles I can imagine that Andy'd be a part of would be primitive survivalists, and people who believe they've been Satanically ritually abused." Randy says this mindlessly, as if his mouth is a mechanical teletype hammering out a weather forecast. It kind of hangs there. "That helps fill in a few gaps," Tom finally says. "What did you think when the FBI searched his cabin?" Cantrell asks, his grin returned. "I didn't know what to think," Randy says. "I remember watching the videotape on the news the agents coming out of that shack with boxes of evidence, and thinking my name must be on papers in them. That somehow I'd get mixed up in the case as a result." "Did the FBI ever contact you?" Tom asks. "No. I think that once they searched through all of his stuff, they figured out pretty quickly that he wasn't the Digibomber, and crossed him off the list." "Well, not long after that happened, Andy Loeb showed up on the Net," Cantrell says. "I find that impossible to believe." "So did we. I mean, we'd all received copies of his manifestoes printed on this grey recycled paper that was like the sheets of fuzz that you peel off a clothes dryer's lint trap." "He used some kind of organic, water based ink that flaked off like black dandruff," Tom says. "We used to joke about having Andy grit all over our desks," Cantrell says. "So when this guy called Andy Loeb showed up on the Secret Admirers mailing list, and the Eutropia newsgroup, posting all of these long rants, we refused to believe it was him." "We thought that someone had just written really brilliant parodies of his prose style," Cantrell says. "But when they kept coming, day after day, and he started getting into these long dialogs with people, it became obvious that it really was him," Tom grumbles. "How did he square that with being a Luddite?" Cantrell: "He said that he'd always thought of computers as a force that alienated and atomized society." Tom: "But as the result of being the number one Digibomber suspect for a while, he'd been forcibly made aware of the Internet, which changed computers by connecting them." "Oh, my god!" Randy says. "And he'd been mulling over the Internet while he was doing whatever Andrew Loeb does," Tom continues. Randy: "Squatting naked in icy mountain streams strangling muskrats with his bare hands." Tom: "And he'd realized computers could be a tool to unite society." Randy: "And I'll bet he was just the guy to unite it." Cantrell: "Well, that's actually not far away from what he said." Randy: "So, are you about to tell me that he became a Eutropian?" Cantrell: "Well, no. It's more like he discovered a schism in the Eutropian movement we didn't know was there, and created his own splinter group. Randy: "I think of the Eutropians as being totally hard core individuals, pure libertarians." "Well, yeah!" Cantrell says. "But the basic premise of Eutropianism is that technology has made us post human. That Homo sapiens plus technology is effectively a whole new species: immortal, omnipresent because of the Net, and headed towards omnipotence. Now, the first people to talk that way were libertarians." Tom says, "But the idea has attracted all kinds of people including Andy Loeb. He showed up one day and started yammering about hive minds." "And of course he was flamed to a crisp by most of the Eutropians, because that concept was anathema to them," Cantrell says. Tom: "But he kept at it, and after a while, some people started agreeing with him. Turned out there was really a pretty substantial faction within the Eutropians who didn't especially care for libertarianism and who found the idea of a hive mind attractive." "So, now Andy's the leader of that faction?" Randy asks. "I would suppose so," Cantrell says. "They split away and formed their own newsgroup. We haven't heard much from them in the last six months or so." "So how did you become aware of a connection between Andy and me?" "He stills pops into the Secret Admirers newsgroup from time to time," Tom says. "And there's been a lot of discussion there about the Crypt lately." Cantrell says, "When he found out that you and Avi were involved, he posted this vast rant twenty or thirty K of run on sentences. Not very complimentary." "Well, Jesus. What's his beef? He won the case. Completely bankrupted me. You'd think he'd have something better to do than beat this dead horse," Randy says, thumping himself on the chest. "Doesn't he have a day job?" "He's some kind of a lawyer now," Cantrell says. "Ha! Figures." "He's been denouncing us," Tom says. "Capitalist roader. Atomizing society. Making the world safe for drug traffickers and Third World kleptocrats." "Well, at least he got something right," Randy says. He's delighted to have an answer, finally, to the question of why they're building the Crypt. Chapter 27 RETROGRADE MANEUVER Sio is a mud cemetery. Those who have already given their lives for the emperor compete for mire space with those who intend to. Bizarre forktailed American planes dive out of the sun every day to murder them with terrible glowing rains of cannon fire and the mind crushing detonations of bombs, so they sleep in open topped graves and only come out at night. But their pits are full of reeking water that chums with hostile life, and when the sun goes down, rain beats them, carrying into their bones the deadly chill of high altitudes. Every man in the 20th Division knows that he will not leave New Guinea alive, so it remains only to choose the method of death: surrender to be tortured, then massacred by the Australians? Put grenades to their heads? Remain where they are to be killed by the airplanes all day, and all night by malaria, dysentery, scrub typhus, starvation, and hypothermia? Or walk two hundred miles over mountains and flooding rivers to Madang, which is tantamount to suicide even when it is peacetime and you have food and medicine...? But that is what they are ordered to do. General Adachi flies to Sio it is the first friendly plane they have seen in weeks and lands on the rutted septic field that they call an airstrip, and orders the evacuation. They are to move inland in four detachments. Regiment by regiment, they bury their dead, pack up what is left of their equipment, hoard what little food is left, wait for dark, and trudge towards the mountains. The later echelons can find their path by smell, following the reek of dysentery and of the corpses dropped behind the pathfinder groups like breadcrumbs. The top commanders stay to the end, and the radio platoon stays with them; without a powerful radio transmitter, and the cryptographic paraphernalia that goes with it, a general is not a general, a division is not a division. Finally they go off the air, and begin breaking the transmitter down into the smallest pieces they can, which unfortunately are not all that small; a divisional radio transmitter is a powerful beast, made for lighting up the ionosphere. It has an electrical generator, transformers, and other components that cannot be made light. The men of the radio platoon, who would find it difficult to move even the weight of their own skeletons over the mountains and across the surging rivers, will carry the additional burdens of engine blocks, fuel tanks, and transformers. And the big steel trunk with all of the Army codebooks. These books were heavy as death when they were bone dry; now they are sodden. To carry them out is beyond imagining. The rules dictate that they must therefore be burned. The men of the 20th Division's radio platoon are not much inclined to humor of any kind at the moment, not even the grim sardonic humor universal among soldiers. If anything in the world is capable of making them laugh at this moment, it is the concept of trying to construct a bonfire out of saturated codebooks in a swamp during a rainstorm. They might be able to burn them if they used a lot of aviation fuel more than they actually have. Then the fire would produce a towering column of smoke that would draw P 38s as the scent of human flesh draws mosquitoes. Burning them can't be necessary. New Guinea is a howling maelstrom of decay and destruction; the only things that endure are rocks and wasps. They rip off the covers to bring home as proof that they have been destroyed, then pack the books into their trunk and bury it in the bank of an especially vindictive river. It's not a very good idea. But they have been getting bombed a lot. Even if the shrapnel misses you, the bomb's shock wave is like a stone wall moving at seven hundred miles an hour. Unlike a stone wall, it passes through your body, like a burst of light through a glass figurine. On its way through your flesh, it rearranges every part of you down to the mitochondrial level, disrupting every process in every cell, including whatever enables your brain to keep track of time and experience the world. A few of these detonations are enough to break the thread of consciousness into a snarl of tangled and chopped filaments. These men are not as human as they were when they left home; they cannot be expected to think clearly or to do things for good reasons. They throw mud on the trunk not as a sane procedure for getting rid of it but as a kind of ritual, just to demonstrate the proper respect for its lode of strange information. Then they shoulder their burdens of iron and rice and begin to strain up into the mountains. Their comrades have left a trampled path that is already growing back into jungle. The mileposts are bodies by now just stinking battlegrounds disputed by frenzied mobs of microbes, bugs, beasts, and birds never catalogued by scientists. Chapter 28 HUFFDUFF The huffduff mast is planted before they even have a roof on the new headquarters of Detachment 2702, and the huffduff antenna is raised before there is any electricity to run it. Waterhouse does his best to pretend as if he cares. He lets the workers know: vast tank armadas clashing in the African desert might be dashing and romantic, but the real battle of this war (ignoring, as always, the Eastern Front) is the Battle of the Atlantic. We can't win the Battle of the Atlantic without sinking some U boats, and we can't sink them until we find them, and we need a way of finding them other than the tried and true approach of letting our convoys steam through them and get blown to bits. That way, men, is to get this antenna in action as soon as humanly possible. Waterhouse is no actor, but when the second ice storm of the week blows through and inflicts grievous damage on the antenna, and he has to stay up all night repairing it by the light of the Galvanick Lucifer, he is pretty sure that he has them hooked. The castle staff work late shifts to keep him supplied with hot tea and brandy, and the builders give him some zesty hip hip hoorays the next morning when the patched antenna is winched back up to the top of the mast. They are all so sure that they are saving lives in the North Atlantic that they would probably lynch him if they knew the truth. This huffduff story is ridiculously plausible. It is so plausible that if Waterhouse were working for the Germans, he'd be suspicious. The antenna is a highly directional model. It receives a strong signal when pointed towards the source and a weak signal otherwise. The operator waits for a U boat to begin transmitting and then swings the antenna back and forth until it gives the maximum reading; the direction of the antenna then gives the azimuth to the source. Two or more such readings, supplied by different huffduff stations, can be used to triangulate the origin of the signal. In order to keep up appearances, the station needs to be manned 24 hours a day, which almost kills Waterhouse during the first weeks of 1943. The rest of Detachment 2702 has not shown up on schedule, so it is up to Waterhouse to preserve the illusion in the meantime. Everyone within ten miles basically, the entire civilian population of Qwghlm, or, to put it another way, the entire Qwghlmian race can see the new huffduff antenna rising from the mast on the castle. They are not stupid people and some of them, at least, must understand that the damn thing doesn't do any good if it is always pointed in the same direction. If it's not moving, it's not working. And if it's not working, then just what the hell is going on up there in the castle anyway? So Waterhouse has to move it. He lives in the chapel, sleeping when he sleeps in a hammock strung at a perilous altitude above the floor ("skerries" are excellent jumpers, he has found). If he sleeps during the daytime, even casual observers in the town will notice that the antenna does not move. That's no good. But he can't sleep at night, when the Germans bounce their transmissions off the ionosphere between the U boats in the North Atlantic and their bases in Bordeaux and Lorient because a really close observer say an insomniacal castle worker, or a German spy up in the rocks with a pair of binoculars will suspect that the immobile huffduff antenna is just a cover story. So Waterhouse tries to split the difference by sleeping for a few hours around dusk and another few hours around dawn a plan that does not go over well with his body. And when he gets up, he has absolutely nothing to look forward to besides sitting at the huffduff console for eight or twelve hours at a stretch, watching the breath come out of his mouth, twiddling the antenna, listening to nothing! He freely stipulates that he is a selfish bastard for feeling sorry for himself when other men are being blown to bits. Having gotten that out of the way, what is he going to do to stay sane? He has got his routine down pat: leave the antenna pointed generally westwards for a while, then swing it back and forth in diminishing arcs, pretending to zero in on a U boat, then leave it sitting for a while and do jumping jacks to warm back up. He has ditched his uniform for raiments of warm Qwghlmian wool. Every once in a while, at totally unpredictable intervals, members of the castle staff will burst in on him with an urn of soup or tea service or simply to see how he is doing and tell him what a fine chap he is. Once a day, he writes down a bunch of gibberish his purported results and dispatches it over to the naval base. He divides his time between thinking about sex and thinking about mathematics. The former keeps intruding upon the latter. It gets worse when the stout fiftyish cook named Blanche, who has been bringing him his meals, comes down with dropsy or ague or gout or colic or some other Shakespearian ailment and is replaced by Margaret, who is about twenty and quite fetching. Margaret really messes up his head. When it gets really intolerable, he goes to the latrine (so that the staff will not break in on him at an inopportune moment) and executes a Manual Override. But one thing he learned in Hawaii was that a Manual Override is unfortunately not the same as the real thing. The effect wears off too soon. While he's waiting for it to wear off, he gets a lot of solid math done. Alan provided him with some notes on redundancy and entropy, relating to the voice encryption work he is currently doing in New York City. Waterhouse works through that stuff and comes up with some nice lemmas which he lamentably cannot send to Alan without violating both common sense and any number of security procedures. This done, he turns his attention to cryptology, pure and raw. He spent enough time at Bletchley Park to realize just how little of this art he really understood. The U boats talk on the radio way too much and everyone in the German Navy knows it. Their security experts have been nagging their brass to tighten up their security, and they finally did it by introducing the four rotor version of the Enigma machine, which has knocked Bletchley Park on its ass for about a year... Margaret has to walk round the castle out of doors to bring Waterhouse his meals, and by the time she gets here, her cheeks have turned rosy red. The steam coming from her mouth floats around her face like a silken veil Stop that, Lawrence! The subject of today's lecture is the German Naval four wheel Enigma, known to them as Triton and to the Allies as Shark. Introduced on 2 February of last year (1942), it wasn't until the recovery of the beached German U boat U 559 on 30 October that Bletchley Park got the material they needed to break the code. A couple of weeks ago, on 13 December, Bletchley Park finally busted Shark, and the internal communications of the German Navy became an open book to the Allies once more. The first thing they have learned, as a result, is that the Germans have broken our merchant shipping codes wide open, and that all year long they have known exactly where to find the convoys. All of this information has been provided to Lawrence Pritchard Waterhouse within the last few days, via the totally secure one time pad channel. Bletchley is telling him this stuff because it raises a question of information theory, which is his department and his problem. The question is: how quickly can we replace our busted merchant shipping codes without tipping the Germans off to the fact that we have broken Shark? Waterhouse does not have to think about this one for very long before he concludes that it is far too tricky to play games with. The only way to handle the situation is to concoct an incident of some sort that will explain to the Germans why we have totally lost faith in our own merchant shipping codes and are changing them. He writes up a message to this effect, and begins to encrypt it using the one time pad that he shares with Chattan. "Is everything quite all right?" Waterhouse stands and whirls around, heart thrashing. It is Margaret, standing there veiled in the steam of her own breath, a grey wool overcoat thrown over her maid's uniform, supporting a tray of tea and scones with grey wool mittens. The only parts of her not encased in wool are her ankles and her face. The former are well turned; Margaret is not above wearing heels. The latter has never been exposed to the direct rays of the sun and brings to mind rose petals strewn over Devonshire clotted cream. "Oh! Let me take it!" Waterhouse blurts, and lunges forward with a jerkiness born of passion blended with hypothermia. While taking the tray from her hands, he inadvertently pulls off one of her mittens, which falls to the floor. "Sorry!" he says, realizing he has never seen her hands before. She has red polish on the nails of the offended hand, which she cups over her mouth and blows on. Her large green eyes are looking at him, full of placid expectation. "Beg pardon?" Waterhouse says. "Is everything quite all right?" she repeats. "Yes! Why shouldn't it be?" "The antenna," Margaret says. "It hasn't moved in over an hour." Waterhouse is so flummoxed he can barely remain standing. Margaret is still breathing through her lacquered fingertips, so that Waterhouse can only see her green eyes, which now angle and twinkle mischievously. She glances towards his hammock. "Been napping on the job, have we?" Waterhouse's first impulse is to deny it and to explain the truth, which is that he was thinking about sex and crypto and forgot to move the antenna. But then he realizes that Margaret has supplied him with a better excuse. "Guilty as charged," he says. "Was up late last night." "That tea will keep you alert," Margaret says. Then her eyes return to the hammock. She pulls her mitten back on. "What is it like?" "What is what like?" "Sleeping in one of those. Is it comfortable?" "Very comfortable." "Can I just see what it's like?" "Ah. Well, it's very difficult to get in at that height." "You manage it, though, don't you?" she says chidingly. Waterhouse feels himself blushing. Margaret walks over to the hammock and kicks off her heels. Waterhouse winces to see her bare feet on the stone floor, which has not been warm since the Barbary Corsairs burned the place down. Her toenails are also painted red. "I don't mind it," Margaret says, "I'm a farmer's daughter. Come on, give me a leg up!" Waterhouse has completely lost whatever control he might ever have had over the situation and himself. His tongue seems to be made of erectile tissue. So he lumbers over, bends down, and makes a stirrup of his hands. She puts her foot into it and launches herself into the hammock, disappearing with a whoop and a giggle into his bulky nest of grey wool blankets. The hammock swings back and forth across the center of the chapel, like a censer dispersing a faint lavender scent. It swings once, twice. It swings five times, ten times, twenty. Margaret is silent and motionless. Waterhouse stands as if his feet were planted in mortar. For the first time in weeks he does not know exactly what is going to happen next, and the loss of control leaves him stunned and helpless. "It's dreamy," she says. Dreamily. Then, finally, she shifts. Waterhouse sees her little face peeking out over the edge, shrouded in the grey cowl of a blanket. "Ooh!" she screams, and flips flat on her back again. The sudden movement puts an eccentric jiggle into the rhythmic motion of the hammock. "What's wrong?" Waterhouse says hopelessly. "I'm afraid of heights!" she exclaims. "I'm so sorry, Lawrence, I should have warned you. Is it all right if I call you Lawrence?" She sounds as if she would be terribly hurt if he said no. And how can Lawrence wound the feelings of a pretty, barefoot, acrophobic girl, helpless in a hammock? "Please. By all means," he says. But he knows perfectly well that the ball is still in his court. "Can I be of any assistance?" "I should be so obliged," Margaret says. "Well, would you like to climb down onto my shoulders, or some thing?" Waterhouse essays. "I'm really far too terrified," she says. There is only one way out. "Well. Would you take it the wrong way if I came up there to help?" "It would be so heroic of you!" she says. "I should be unspeakably grateful." "Well, then . . ." "But I insist that you continue with your duties first!" "Beg pardon?" "Lawrence," Margaret says, "when I get down from this hammock I shall go to the kitchen and mop the floor which is already quite clean enough, thank you. You, on the other hand, have important work to do work that might save the lives of hundreds of men on some Atlantic convoy! And I know that you have been very naughty in sleeping on the job. I refuse to allow you up here until you have made amends." "Very well," Waterhouse says, "you leave me no alternative. Duty calls." He squares his shoulders, spins on his heel, and marches back to his desk. Skerries have already made off with all of Margaret's scones, but he pours himself some tea. Then he resumes encrypting his instructions to Chattan: ONLY BRUTE FORCE APPROACH WILL BE SAFE PUT CODE BOOK ON SHIP INSERT SHIP IN MURMANSK CONVOY WAIT FOR FOG RAM NORWAY. The one time pad encryption takes a while. Lawrence can do mod 25 arithmetic in his sleep, but doing it with an erection is a different matter. "Lawrence? What are you doing?" Margaret asks from her nest in the hammock, which, Lawrence imagines, is getting warmer and cozier by the minute. He glances surreptitiously at her discarded high heels. "Preparing my report," Lawrence says. "Doesn't do me any good to make observations if I don't send them out." "Quite right," Margaret says thoughtfully. This is an excellent time to stoke the chapel's pathetic iron stove. He puts in a few scoops of precious coal, his worksheet, and the page from the one time pad that he has just used to do the encryption. "Should warm up now," he says. "Oh, lovely," Margaret says, "I'm all shivery." Lawrence recognizes this as his cue to initiate a rescue operation. About fifteen seconds later, he is up there in the hammock with Margaret. To the great surprise of neither one of them, the quarters are awkward and tight. There is some flopping around which ends with Lawrence on his back and Margaret on top of him, her thigh between his. She is shocked to discover that he has an erection. Ashamed, apparently, that she did not anticipate his need. "You poor dear!" she exclaims. "Of course! How could I have been so dense! You must have been so lonely here." She kisses his cheek, which is nice since he is too stunned to move. "A brave warrior deserves all the support we civilians can possibly give him," she says, reaching down with one hand to open his fly. Then she pulls the grey wool over her head and burrows to a new position. Lawrence Pritchard Waterhouse is stunned by what happens next. He gaze
