'Buenos Aires? Sweden?'
'Yes. And so, Alan, I took an interest in Arethusa.'
'Well, I don't blame you!'
'The message format matches that of Azure/Pufferfish.'
'Rudy's system?'
'Yes.'
'Nice work on that, by the way.'
'Thank you, Alan. As you must have heard by now, it is based on zeta functions. Which you did not even consider using for Delilah because you were afraid Rudy would think of it. And this raises the question of whether Rudy intended us to break Azure/Pufferfish all along.'
'Yes, it does. But why would he want us to?'
'I have no idea. The old Azure/Puffeffish messages may contain some clues. I am having my Digital Computer generate retroactive one-time pads so that I can decrypt those messages and read them.'
'Well, then, I shall have Colossus do the same. It is busy just now,' Alan says, 'working on Fish decrypts. But I don't think Hitler has much longer to go. When he is finished, I can probably get down to Bletchley and decrypt those messages.'
'I'm also working on Arethusa,' Lawrence says. 'I'm guessing it all has something to do with gold.'
'Why do you say that?' Alan says. But at this point the tone arm of the phonograph reaches the end of its spiral groove and lifts off the record. Time's up. Bell Labs, and the might of the Allied governments, did not install the Project X network so that mathematicians could indulge in endless chitchat about obscure functions.
Chapter 94 LANDFALL
The sailing ship Gertrude wheezes into the cove shortly after sunrise, and Bischoff cannot help but laugh. Barnacles have grown so thick around her hull that the hull itself (he supposes) could be removed entirely, and the shell of barnacles could be outfitted with a mast and canvas, and sailed to Tahiti. A hundred-yard-long skein of seaweed, rooted in those barnacles, trails behind her, making a long greasy disturbance in her wake. Her mast has evidently been snapped off at least once. It has been replaced by a rude jury-rigged thing, a tree trunk that has received some attention from a drawknife but still has bark adhering to it in places, and long dribbles of golden sap like wax trails on a candle, themselves streaked with sea salt. Her sails are nearly black with dirt and mildew, and rudely patched, here and there, with fat black stitches, like the flesh of Frankenstein's monster.
The men on board are scarcely in better shape. They do not even bother to drop anchor-they just run Gertrude

Bischoff clicks his heels together sharply and holds out his right arm. 'Heil Donitz!' he shouts.
'What the hell are you talking about?' asks Otto.
'Haven't you been reading the papers? Hitler killed himself yesterday. In Berlin. The new Fuhrer is my personal friend Karl Donitz.'
