"Each of these numbers is a code," Cayce says, "identifying a particular sequence in a piece of information. Each sequence has one of these numbers encrypted, for purposes of identification, and to enable it to be tracked."
"Stego," says Baranov, putting a slender, brown-stained forefinger down on the printout. "This one. Why's it circled?"
"The encryption is done by a firm in America called Sigil. I want to learn who they do it for, but the specific piece of information I'm asking you for is the e-mail address to which they sent this particular piece, when it had been encrypted."
Sigil?
"In Ohio."
He sucks his teeth, making an odd, small, birdlike sound.
"Can you do that?"
"Protocol," he says. "Assuming I could, what then?"
"If you tell me you can, I'll go to your dealer and buy the calculator."
"And then?"
"You'll give me the e-mail address."
"And then?"
"I'll give Ngemi the calculator. But if you don't give me the address…"
"Yes?"
"It goes into the canal, at Camden Lock."
He leans forward, eyes narrowing behind round lenses, lost in an intricacy of wrinkles. "You'd do that, would you?"
"Yes. And I'll do it if I think you're cheating me."
He peers at her. "I believe you would," he says, at last, with something close to approval.
"Good. Then call Ngemi, when you have something. He knows how to reach me."
He says nothing.
"Thank you for considering my offer." She rises, crouching beneath the low ceiling, elbowing open the door, and climbs out, into bright pallor and rich, extraordinarily fresh air. "Goodbye." She closes the door behind her.
Ngemi creaks, beside her. "Was he in a better mood, then?" he asks.
"He showed me his gun."
"This is England, girl," Ngemi says. "People don't have guns."

On the train to Waterloo, Ngemi buys beer and a packet of chicken-flavored crisps from the refreshment cart.
Cayce buys a bottle of still mineral water.
"How did Baranov wind up that way?" she asks.
"In that specific place?"
"In his general situation. Did he drink himself there?"
"I had a cousin, back home," says Ngemi, "who drank an entire electrical appliance business. He was otherwise an ordinary fellow, well liked. His problem seemed simply the drink. With Hobbs, I imagine the drink might be a symptom of something else, though so established now that it hardly matters. Hobbs is his mother's maiden name. Hobbs-Baranov, hyphenated at birth. His father, a Soviet diplomat, defected in the fifties to America, marrying an Englishwoman of considerable wealth. Hobbs managed to lose the hyphen, but when drunk he still rails against it. He once told me that he'd lived his whole life within that hyphen, in spite of having buried it."
"He worked for American intelligence, as a mathematician?"
"Recruited from Harvard, I believe. But again, it's difficult to know. He only mentions those things when drunk." He pops the top on his can of beer, and sips. "I suppose I have no business asking, but was your visit a success?"
"It may have been. But I'll have to ask for more of your help, if it was."
"Can you tell me more?"
"I need something, and Baranov may be able to find it for me. In ex-change, I've offered to buy that calculator for him, from the dealer in Bond Street."
"Greenaway? His asking price is obscene."
"It doesn't matter. If Baranov gets me what I want, it's a bargain."
"And you need my help?"
"I need you to go with me, to this dealer, and help me buy it. Make sure it's the right one, the one Baranov wants. And if Baranov gives me what I want, I'll need you to deliver it to him."
"I can do that, certainly."
"How do we start?" '
"Greenaway has a website. He doesn't open, Sundays."
She opens the Luggage Label and removes her iMac and phone. "I hope it's still there, the calculator."
"It will be," Ngemi assures her, "at Greenaway's price."
THE evening version of a Waterloo Sunday moves differently, and the pigeons Cayce had seen flying, that morning, now race fearlessly amid the feet of hurrying passengers, pecking up the day's bounty.
Under Ngemi's tutelage, she's e-mailed Greenaway, asking for the Curta prototype, which is indeed still on offer, to be placed on hold, prior to her viewing it tomorrow, with intent to buy. "The hold is no protection," Ngemi explains, as she walks with him toward the escalators, "should another tragic victim turn up in the meantime, but it will serve to get his attention, and establishes a certain tone. It will help that he knows you are American." He had insisted she mention that she was from New York, and only in London briefly. "Do you know when Hobbs might have your information for you?"
"No idea."
"But you wish to go ahead with Greenaway?"
"Yes."
"You are not a wealthy woman?"
"Not at all. I'm using someone else's money."
"If you had offered Hobbs the amount of Greenaway's price, in cash, he might well have refused you. He could no more pay Greenaway's price, with his own money, than I could. I've known him to refuse offers, for that sort of service, that I took to be much larger."
"But doesn't he need money anyway, or want it?"
