"Anyone else?" Mallory said.

"Well, the Royal Family, of course. We are servants of the Crown here, after all. If Albert himself were to command our Minister of Statistics…"

"What about the Prime Minister? Lord Byron?"

Tobias made no reply. His face had soured.

"An idle question," Mallory said. "Forget I asked it. It's a scholar's habit, you see—when a topic interests me, I explore its specifics, even to the point of pedantry. But it has no relevance here." Mallory peered at the pictures again, with a show of close attention. "No doubt it is my own fault—the light here is not all it might be."

"Let me turn up the gas," the boy said, half-rising.

"No," Mallory said. "Let me save my attention for the woman. Perhaps we'll have better luck there."

Tobias sank back in his seat. As they awaited the Engine-spin, Mallory feigned a relaxed indifference. "Slow work, eh, Mr. Tobias? A lad of your intelligence must long for a greater challenge."

"I do love Engines," Tobias said. "Not these great lummox monsters, but the cleverer, aesthetic ones. I wanted to learn clacking."

"Why aren't you in school, then?"

"Can't afford it, sir. The family doesn't approve."

"Did you try the National Merit Exams?"

"No scholarship for me—I failed the calculus." Tobias looked sullen. "I'm no scientist, anyway. It's art that I live for. Kinotropy!"

"Theatre work, eh? They say it's in the blood."

"I spend every spare shilling on spinning-time," the boy said. "We have a little club of enthusiasts. The Palladium rents its kinotrope to us, during the wee hours. You see quite amazing things, sometimes, along with a deal of amateur drivel."

"Fascinating," Mallory said. "I hear that, er…" He had to struggle to recall the man's name. "I hear that John Keats is quite good."

"He's old," the boy said, with a ruthless shrug. "You should see Sandys. Or Hughes. Or Etty! And there's a clacker from Manchester whose work is quite splendid—Michael Radley. I saw a show of his here in London, last winter. A lecture tour, with an American."

"Kinotrope lectures can be very improving."

"Oh, the speaker was a crooked Yankee politician. If I had my way, they'd throw the speaker out entirely, and run silent pictures."

Mallory let the conversation lapse. Tobias squirmed a bit, wanting to speak again and not quite daring to take that liberty, and then the bell rang. The boy was up like a shot, with a scratchy skid of his worthless shoes, and back with another set of fan-fold paper.

"Red-heads," he said, and smiled sheepishly.

Mallory grunted. He studied the women with close attention. They were fallen women, ruined women, with the sodden look of fall and ruin marked indelibly in the little black picture-bits of their printed femininity. Unlike the men, the female faces somehow leapt to life for Mallory. Here a round-faced Cockney creature, with a look more savage than a Cheyenne squaw. There a sweet-eyed Irish girl whose lantern jaw had surely embittered her life. There a street-walker with rat's-nest hair and the blear of gin. There, defiance; here, tight-lipped insolence; there, a frozen cajoling look from an Englishwoman with her nape pinched for too long in the daguerreotype's neck-brace.

The eyes, with their calculated plea of injured innocence, held him with a shock of recognition. Mallory tapped the paper, looking up. "Here she is!"

Tobias started. "That's rum, sir! Let me take that number." He punched the citizen-number into a fresh card with a small mahogany switch-press, then fed the card through the wall-tray again. He carefully emptied the bits of punched-out paper into a hinge-topped basket.

"This will tell me all about her, will it?" Mallory said. He reached inside his jacket for his notebook.

"Mostly, sir. A printed summary."

"And may I take these documents away with me for study?"

"No, sir, strictly speaking, as you're not an officer of the law… " Tobias lowered his voice. "Truth to tell, sir, you could pay a common magistrate, or even his clerk, and have this intelligence for a few shillings, under the rose. Once you've someone's number, the rest is simple enough. It's a common clacker trick, to read the Engine-files on someone of the criminal class—they call it 'pulling his string,' or being 'up on a cake.' "

Mallory found this news of remarkable interest. "Suppose I asked for my own file?" he said.

"Well, sir, you're a gentleman, not a criminal. You're not in the common police-files. Your magistrates, and court-clerks and such, would have to fill out forms, and show good cause for the search. Which we don't grant easily."

"Legal protocols, eh?" Mallory said.

"No, sir, it's no law that stops us, but the simple trouble of it. Such a search consumes Engine-time and money, and we're always over budget in both. But if an M.R made that request, or a Lordship…"

"Suppose I had a good friend here in the Bureau," Mallory said. "Someone who admired me for my generous ways."

Tobias looked reluctant, and a bit coy. "It ain't a simple matter, sir. Every spinning-run is registered, and each request must have a sponsor. What we did today is done in Mr. Wakefield's name, so there'll be no trouble in that. But your friend would have to forge some sponsor's name, and run the risk of that imposture. It is fraud, sir. An Engine-fraud, like credit-theft or stock-fraud, and punished just the same, when it's found out."

"Very enlightening," Mallory said. "I've found that one always profits by talking to a technical man who truly knows his business. Let me give you my card."

Mallory extracted one of his Maull & Polyblank cartes-de-visite from his pocket-book. Folding a five-pound note, he pinched it against the back of his card and passed it over. It was a handsome sum. A deliberate investment.

Tobias dug about beneath his apron, found a greasy leather wallet, stuffed in Mallory's card and money, and extracted a dog-eared bit of shiny pasteboard. J. J. TOBIAS, ESQ. , the card said, in grotesquely elaborate Engine-Gothic. KINOTROPY, AND THEATRE COLLECTIBLES. There was a Whitechapel address. "Never mind that telegraph number at the bottom," Tobias told him. "I had to stop renting it."

"Have you any interest in French kinotropy, Mr. Tobias?" Mallory said.

"Oh, yes, sir," nodded Tobias. "Some lovely material is coming out of Montmartre these days."

"I understand the best French ordinateurs employ a special gauge of card."

"The Napoleon gauge," Tobias said readily. "Smaller cards of an artificial substance, which move very swiftly in the compilers. That speed is quite handy in kino-work."

"Do you know where a fellow might rent one of these French compilers, here in London?"

"To translate data from French cards, sir?"

"Yes," Mallory said, feigning an only casual interest. "I expect to receive some data from a French colleague, involving a scientific controversy—rather abstruse, but still a matter of some scholarly confidentiality. I prefer to examine it privately, at my own convenience."

"Yes, sir," Tobias said. "That is to say, I do know a fellow with a French compiler, and he'd let you do whatever you like with it, if the pay were right. Last year, there was quite a mode in London clacking-circles for the French standard. But sentiment has turned quite against it, what with the troubles of the Grand Napoleon."

"Really," Mallory said.

Tobias nodded, delighted to show his authority. "I believe it's felt now, sir, that the French were far ahead of themselves with their vast Napoleon project, and made something of a technical misstep!"

Mallory stroked his beard. "That wouldn't be British professional envy talking, I hope."

"Not at all, sir! It's common knowledge that the Grand Napoleon suffered some dire mishap early this year," Tobias assured him, "and the great Engine has never spun quite properly since." He lowered his voice. "Some claim sabotage! Do you know that French term, sabotage" Comes from 'sabots,' the wooden shoes worn by French workers. They can kick an Engine half off its blocks!" Tobias grinned at this prospect, with a glee that rather disquieted Mallory. "The French have Luddite troubles of a sort, you see, sir, much as we once did, years ago!"
