“I don’t know,” said Hollis. The phone rang.

“There you go,” said Heidi, and winked.

“Hello?”

“Welcome back.” Bigend’s voice filled the room. “I’m on my way back to the office. Can you join me there, please? We should talk.”

Hollis looked up at Heidi, tears starting to come. Then back down at the phone.

“Hello?” said Bigend. “Are you there?”

His room here overlooked a canal. He’d only been vaguely aware of London having canals, before. It didn’t have them to the extent that Amsterdam did, or Venice, but it did have them. They were a sort of backdoor territory, evidently. Shops and houses didn’t seem to have faced them. Like a system of aquatic alleys, originally for heavy transport. Now, to judge by the view from his window, they were repurposed as civic and tourist space. Turned into a framework for boat rides, with paths for jogging and cycling. He thought of the boat on the Seine, with its video screen, the Dottirs and George’s band, the Bollards. The boat he’d seen here, earlier, had been much smaller.

The room phone rang. He left the bathroom to answer it. “Hello?”

“I am Voytek,” a man said, with some accent that caused Milgrim, on the off chance, to repeat himself in Russian.

“Russian? I am not Russian. You are?”

“Milgrim.”

“You are American.”

“I know,” said Milgrim.

“My shop,” said Voytek, whose name Milgrim now remembered from brunch in Southwark, “is in market, near your hotel. Under, in old stables. You bring your unit now.”

“What’s the name of your shop?”

“Biro Shack.”

“Biro Shack? Like the pen?”

“Biro Shack. And son. Goodbye.”

“Goodbye.” Milgrim returned the phone to its cradle.

He sat down at the desk and logged into his Twitter account.

“Get n touch,” Winnie had posted, an hour earlier.

“Camden Town Holiday Inn,” he typed, then added his room number and the telephone number of the hotel. He updated. Refreshed. Nothing.

The phone rang.

“Hello?”

“Welcome back,” said Winnie. “I’m coming over there.”

“I’m just going out,” said Milgrim. “It’s work. I don’t know how long it’s going to take.”

“How’s your evening look?”

“Nothing scheduled yet.”

“Keep it open for me.”

“I’ll try.”

“I’m not that far away. Heading for the general vicinity now.”

“Goodbye,” Milgrim said to the phone, though she was already gone. He sighed.

He’d forgotten to return Hollis’s red dongle, but he didn’t need it here. He’d give it back to her the next time he saw her.

He closed the laptop and put it in his bag, which he’d unpacked on arrival. Bigend had wanted the memory card with the pictures of Foley, and he didn’t have another, so he wouldn’t bother taking the camera.

Walking from his room to the elevator, he wondered why they had decided to build a Holiday Inn here, beside this canal.

In the lobby, he waited at the concierge desk while two young American men received directions to the Victoria and Albert. He looked at them the way he imagined Blue Ant’s young French fashion analyst might. Everything they were wearing, he decided, qualified as what she’d call “iconic,” but had originally become that way through its ability to gracefully patinate. She was big on patination. That was how quality wore in, she said, as opposed to out. Distressing, on the other hand, was the faking of patination, and was actually a way of concealing a lack of quality. Until he’d found himself in Bigend’s apparel-design push, he hadn’t known that anyone thought about clothing that way. He didn’t imagine that anything these two wore was liable to acquire any patina, except under different and later ownership.

When they’d moved on, he asked for directions to Voytek’s Biro Shack, explaining where he’d been told it was.

“I don’t see it listed, sir,” said the concierge, clicking his mouse, “but you aren’t far, if it’s where they told you it would be.” He ballpointed a map in a colored brochure and handed it to Milgrim.

“Thanks.”

Outside, the air smelled differently of exhaust. More diesel? The neighborhood felt theme-parky but downscale, a little like a state fairground before the evening crowds arrive. He passed two Japanese girls eating what seemed to be corn dogs, which heightened the effect.

He was keeping an eye out for Winnie, but if she’d arrived he didn’t see her.

Following the ballpoint line on the concierge’s map, he found himself in a brick-arched under-mall, some Victorian retrofit, stocked mostly with merchandise that reminded him of St. Mark’s Place, though with an odd, semi-Japanese feel, perhaps an appeal to foreign youth-tourism. Further back in this, glassed behind half a brick archway, floridly Victorian gilt lettering announced BIROSHAK amp;SON. A surname, then. As he entered, a bell tinked, bouncing on a long Art Nouveau lily stem of brass, attached to the door.

The shop was densely but tidily packed with small, largely featureless boxes, like old-fashioned TV-top cable units, arrayed on glass shelves. A tall, balding man, about Milgrim’s age, turned and nodded. “You are Milgrim,” he said. “I am Voytek.” There was a battered plastic pennant behind the counter: AMSTRAD, both the name and the logo unfamiliar.

Voytek wore a wool cardigan pieced together from perhaps half a dozen donors, one sleeve plain camel, the other plaid. Under it a silky ecru T-shirt with too many pearl buttons. He blinked behind harsh-looking steel-framed glasses.

Milgrim put his bag on the counter. “Will it take long?” he asked.

“Assuming I find nothing, ten minutes. Leave it.”

“I’d rather stay.”

Voytek frowned, then shrugged. “You think I will put something in it.”

“Do you do that?”

“Some people do,” said Voytek. “PC?”

“Mac,” said Milgrim, unzipping his bag and bringing it out.

“Put it on the counter. I lock up.” He came from behind the counter, wearing those gray felt clogs that reminded Milgrim of the feet of toy animals. He went to the door, slid a bolt into place, and returned. “I hate these Air,” he said, amiably enough, turning the laptop over and producing the first of a number of tiny, very expensive-looking screwdrivers. “They are very bitch, to open.”

“What are all these boxes?” Milgrim asked, indicating the shelves.

“They are computers. Real ones. From the dawn.” He removed the bottom of the Air, with no evident difficulty at all.

“Are they valuable?”

“Valuable? What is true worth?” He put on an elaborate pair of magnifying glasses, with clear colorless frames.

“That’s what I asked you.”

“True worth.” LEDs in the clear temples illuminated the elegantly compacted guts of the Air. “You put a price on romance?”

“Romance?”

“These true computers are the root code. The Eden.”

Milgrim saw that there were still older machines, some actually housed in wood, locked in a large, really quite seriously expensive-looking glass case, rising a good six feet from the floor. The wood-cased typewriter-y device nearest him bore an eye-shaped silk-screened ENIGMA logo. “What are those, then?”

“Before the Eden. Enigma encryption. As called forth by Alan Turing. To birth the Eden. Also on offer, U.S. Army M-209B cipher machine with original canvas field case, Soviet M-125-3MN Fialka cipher machine, Soviet clandestine pocket-sized nonelectronic burst encoder and keyer. You are interested?”

“What’s a burst encoder?”

“Enter message, encrypt, send with inhuman speed as Morse code. Spring-winder. Twelve hundred pounds. Discount for Blue Ant employee, one thousand.”

Someone rapped on the door. A young man with a massive diagonal forelock, wrapped in what appeared to be a bathrobe. He was grimacing with impatience. Voytek sighed, put down the Air, on a battered foam pad that bore the Amstrad logo, and went to open the door, still wearing the illuminated magnifying glasses. The bathrobed boy-Milgrim saw that it was a very thin, very wrinkled sort of overcoat, perhaps cashmere-swept past Voytek without eye contact, to the rear of the shop, and through a door Milgrim hadn’t previously noticed. “Cunt,” said Voytek, neutrally, relocking the door and returning to the Air and the task at hand.
