"What happened?"
"I knocked the scoundrel down," Mallory said.
Oliphant stared at him, then burst into laughter. "You're a man of unexpected resources. Dr. Mallory."
"I might say the same of you, sir." Mallory paused. "I have to tell you, though, I don't believe the man was after me. He'd a girl with him, a track-dolly, the two of them bullying a lady"
"Do go on," Oliphant urged, "this is uncommonly interesting."
"I'm afraid I can't," Mallory said. "The lady in question was a personage. "
"Your discretion, sir," Oliphant said evenly, "does you credit as a gentleman. A knife-attack, however, is a serious crime. Have you not informed the police?"
"No," Mallory said, savoring Oliphant's contained agitation, "the lady again, you see. I feared to compromise her."
"Perhaps," Oliphant suggested, "it was all a charade, calculated to involve you in a supposed gambling-brawl. Something similar was worked on Rudwickwho died, you well recall, in a ratting-den."
"Sir," Mallory said, "the lady was none other than Ada Byron."
Oliphant stiffened. "The Prime Minister's daughter?"
"There is no other."
"Indubitably," Oliphant said, a sudden brittle lightness in his tone. "It does strike me, though, that there are any number of women who resemble Lady Ada, our Queen of Engines being a queen of fashion as well. Thousands of women follow her mode."
"I've never been introduced, Mr. Oliphant, but I've seen her in Royal Society sessions. I've heard her lecture on Engine mathematics. I am not mistaken."
Oliphant took a leather notebook from his jacket, propped it against one knee, and uncapped a reservoir-pen. "Tell me, please, about this incident."
"In strictest confidence?"
"You have my word."
Mallory presented a discreet version of the facts. He described Ada's tormentors, and the circumstances, to the best of his ability, but he made no mention of the wooden case with its French Engine-cards of camphorated cellulose. Mallory considered this a private matter between the Lady and himself; she had burdened
him with the guardianship of this strange object of hers, and he regarded this as a sacred obligation. The wooden case of cards, carefully wrapped in white specimen-linen, lay hidden among the plastered fossils in one of Mallory's private lockers at the Museum of Practical Geology, awaiting his further attention.
Oliphant closed his notebook, put away his pen, and signaled the waiter for drinks. The waiter, recognizing Mallory, brought him a huckle-buff. Oliphant had a pink gin.
"I would like you to meet some friends of mine," Oliphant said. "The Central Statistics Bureau maintain extensive files on the criminal classesanthropometric measurements, Engine-portraits, and so forth. I should like you to try to identify your assailant and his female accomplice."
"Very well," Mallory said.
"You shall be assigned police protection, as well."
"Protection?"
"Not a common policeman, of course. Someone from the Special Bureau. They are very discreet."
"I can't have some copper tagging always at my heels," Mallory said. "What would people say?"
"I worry rather more what they'll say if you were to be found gutted in some passage. Two prominent dinosaur-savants, the both of them mysteriously murdered? The press would run quite wild."
"I need no guard. I'm not frightened of the little pimp."
"He may well be unimportant. We shall at least know that, if you are able to identify him." Oliphant sighed delicately. "No doubt it's all a very trumpery affair, according to the standards of Empire. But I should reckon it as including the command of money; the services, when needed, of that shady sort of Englishman, who lives in the byways of foreign life in London; and lastly, the secret sympathy of American refugees, fled here from the wars that convulse that continent."
"And you imagine that Lady Ada has fallen somehow into this dire business?"
"No, sir, none of it. You may rest assured that that cannot possibly be the case. The woman you saw cannot have been Ada Byron."
"Then I regard the matter as settled," Mallory said. "If you were to tell me Lady Ada's interests were at hazard, I might agree to almost any measure. As things stand, I shall take my own chances."
"The decision is entirely yours, of course," Oliphant said coolly. "And perhaps it is still early in the game to take such stem measures. You have my card? Let me know how matters develop."
"I will."
Oliphant stood. "And remember, should anyone ask, that today we have discussed nothing more than the affairs of the Geographical Society."
"You've yet to tell me the name of your own employers, Mr. Oliphant. Your true employers."
Oliphant somberly shook his long head. "Such knowledge never profits, sir; there is nothing but grief in such questions. If you're wise, Dr. Mallory, you'll have nothing more to do with dark-lanterns. With luck, the whole affair will simply come to nothing, in the end, and will fade away, without trace, as a nightmare does. I shall certainly put your name forward for the Geographical, as I have promised, and I do hope that you will seriously consider my proposal regarding possible uses of the Bow Street Engines."
