Cryptonomicon

'This time we wait as long as we can,' he says.

The next leg is shorter, but it's made more difficult by the pain in their knees. Again Rodolfo goes first. But when Goto Dengo rises up into the next air chamber, about one and a half atmospheres above normal, only Bong and Wing are there.

'Rodolfo missed the opening,' Bong says. 'I think he went too far-up the ventilation shaft!'

Goto Dengo nods. Only a few meters beyond where they turned into this passage is a ventilation shaft that goes all the way to the surface. It has a sharp sideways jog in the middle that Goto put there so that when Captain Noda filled it up with rubble (which he has presumably done by now), the diagonal tunnel-their escape route-would not be blocked. If Rodolfo went up that shaft, he found a cul-de-sac, with no air bubble in the top.

Goto Dengo doesn't have to tell the others that Rodolfo is dead. Bong crosses himself and says a prayer. Then they stay for a while and take advantage of the air that Rodolfo should be sharing. The pain in Goto Dengo's knees becomes sharper, but after a while it plateaus.

'From here, only small changes in altitude, not much need to decompress. Mostly we swim for distance now,' he says. They still have more than three hundred horizontal meters to cover, pierced with four more shafts for air. The last of these doubles as a legitimate ventilation shaft.

So from there on it is just swimming and resting, swimming and resting, until finally the walls of the tunnel peel away from them and they find themselves in Lake Yamamoto.

Goto Dengo breaks the surface and does nothing for a long time but tread water and breathe clean air. It is nighttime, and for the first time in a year, Bundok is quiet, except for the sound of Bong, kneeling on the shore of the lake, making the sign of the cross and mumbling prayers as fast as his lips can move.

Wing has already departed, without so much as a good-bye. This is shocking to Goto Dengo until he realizes what it means: he, too, is free to go. As far as the world knows, he is dead, all of his obligations discharged. For the first time in his life, he can do whatever he wants.

He swims to the shore, gets up on his feet, and starts walking. His knees hurt. He cannot believe that he has come through all of this, and his only problem is sore knees.

Chapter 82 BUST

'Kopi,' Randy says to the flight attendant, then reconsiders, remembering that he is in steerage this time, and getting to a toilet might not be so easy. It's just a little Malaysian Air 757. The flight attendant sees the indecision on his face and wavers. Her face is framed in a gaudy, vaguely Islamic scarf that is the most tokenistic nod to sexual modesty he has ever seen. 'Kopi nyahkafeina,'Randy says, and she beams and pours from the orange carafe. It is not that she doesn't speak English, just that Randy is starting to feel comfortable with the local pidgin. He realizes that this is the first step in a long process that will eventually turn him into one of these cheerful, burly, sunburned expats who infest the airport bars and Shangri-La hotels of the Rim.

Outside his window, the long slender isle of Palawan lies parallel to their flight path. A fogbound pilot could almost get from Kinakuta to Manila by following Palawan's beaches, but that is a moot point on a day like this. Those beaches slope gradually into the transparent waters of the South China Sea. When you're down there planted in the sand, looking at a glancing angle across the waves, it probably doesn't look like much, but from up here you can see straight down through the water for many fathoms, and so all of the islands, and even the coral heads, have skirts that start out dark brown or dun near the water and blend into yellow and finally into swimming-pool blue before eventually fading into the deep blue of the ocean. Every little coral head and sandbar looks like the iridescent eye on a peacock's plume.

After the conversation at Tom Howard's last night, Randy slept in his guest room and then spent most of the day in Kinakuta buying a new laptop, complete with a new hard drive, and transferring all of the data from the drive he salvaged in Los Altos onto the new one, encrypting everything in the process. Considering all of the completely boring and useless corporate documents he has subjected to state-of-the-art encryption, he can't believe he carried the Arethusa stuff around on his hard drive, unencrypted, for several days, and across a couple of national borders. Not to mention the original ETC punch-cards, which now reside in Tom Howard's basement safe. Of course that stuff is encrypted to begin with, but that was done in 1945, and so by modern standards it might as well have been enciphered with a cereal-box decoder ring. Or at least that is what Randy is kind of hoping. Another thing he did this morning was to download the current version of the Cryptonomiconfrom the ftp server where it lives in San Francisco. Randy's never looked at it in detail, but he has heard it contains samples of code, or at least algorithms, that he could use to attack Arethusa. With luck, the very latest public code-breaking techniques in the Cryptonomiconmight match up to the classified technology that Pontifex and his colleagues were employing at the NSA thirty years ago. Those techniques didn't work against the Arethusa messages that they were trying to decrypt, but this was probably only because those messages were random numbers-not the real messages. Now that Randy has what he suspects are the real messages, he may be able to accomplish what Earl Comstock tried and failed to do during the fifties.

They are angling across the terminator-not the robotic assassin of moviedom, but the line between night and day through which our planet incessantly rotates. Looking east, Randy can see over the rim of the world to places where it is dusk, and the clouds catch only the reddest fraction of the sun's light, squatting in darkness but glowing with sullen contained fire like coals in their feathery ruffs of ash. The airplane is still in the daylight, and is assiduously tracked by mysterious bars of rainbow, little spectral doppelgangers-probably some new NSA surveillance technology. Some of the Palawan's rivers run blue and straight into the ocean and some carry enormous plumes of eroded silt that feather out into the ocean and are swept up the shore by currents. In Kinakuta there is less deforestation than there is here, but only because they have oil instead. All of these countries are burning resources at a fantastic rate to get their economies stoked up, gambling that they'll be able to make the jump into hyperspace-some kind of knowledge economy, presumably-before they run out of stuff to sell and turn into Haiti.

Randy is paging his way through the opening sections of the Cryptonomicon,but he can never concentrate when he's on an airplane. The opening sections are stolen pages from World War II-era military manuals. These used to be classified until ten years ago, when one of Cantrell's friends found copies just sitting in a library in Kentucky and drove there with a shitload of dimes and photocopied them. That got public, civilian cryptanalysis up to where the government was in the l940s. The Xeroxes have been scanned and OCRed and converted to the HTML format used for Web pages so that people can put in links and marginal notes and annotations and corrections without messing with the original text, and this they have done enthusiastically, which is all very well but makes it hard to read. The original text is set in a deliberately crabbed, old-fashioned typeface to make it instantly distinguishable from the cyber-era annotations. The introduction to the Cryptonomiconwas written, probably before Pearl Harbor, by a guy named William Friedman, and is filled with aphorisms probably intended to keep neophyte code-breakers from slapping grenades to their heads after a long week of wrestling with the latest Nipponese machine ciphers.

The fact that the scientific investigator works 50 percent of his time by nonrational means is, it seems, quite insufficiently recognized.

Intuition, like a flash of lightning, lasts only for a second. It generally comes when one is tormented by a difficult decipherment and when one reviews in his mind the fruitless experiments already tried. Suddenly the light breaks through and one finds after a few minutes what previous days of labor were unable to reveal.

And, Randy's favorite,

As to luck, there is the old miners' proverb: 'Gold is where you find it.'
