Caswell actually blinked, not having expected such an immediate thrust, but recovered smoothly with a sidestep.

“Trevelyan? I know no one of that name.”

“Oh, you know him. Whether he uses that name here is of no account; you know everything of interest about everyone who comes here. Certainly you know their real surnames.”

“Flatterer,” Caswell said again, though he looked less amused.

“The gentlemen in the library were not reserved,” Grey said, trying for advantage. “If I were to seek them out, outside the confines of your house, I imagine some of them might tell me what I wish to know.”

Caswell laughed, deeply enough to start a small fit of coughing.

“No, they won’t,” Caswell wheezed, groping for a fresh handkerchief. He mopped at his eyes and his shriveled mouth, drawn up in a smile once more. “No doubt one or two would tell you anything they thought you’d like to hear, if it would loosen your breeches, but they won’t tell you that.”

“Won’t they?” Grey affected indifference, sipping at his wine. “Trevelyan’s affairs must be of more importance than I thought, if it’s worth your threatening your members to keep his secrets.”

“Oh, perish the thought, perish the thought!” Caswell flapped a bony hand. “Threats? Me? You know better than that, dear boy. If I were given to threats, I should have ended in the Fleet Ditch with my head caved in, long since.”

A tingle of alertness shot through Grey at this remark, though he fought to keep his face blandly expressionless. Was this mere hyperbole, or warning? Caswell’s withered face gave nothing away, though the sparkling eyes watched his own for any clue to his intent.

He breathed deeply to slow the rapid beating of his heart, and took another sip of wine. It might be nothing more than a coincidence, a mere accident of speech; the Fleet was at hand, after all—and for what it was worth, Caswell was correct: He serviced men of wealth and influence, and if he were given to threats or blackmail, he would have been quietly put out of business long since, in one way or another.

Information, though, was something else. George had once told him that Caswell’s main stock in trade was information—and the profits from Lavender House likely were not great enough to provide the lavish furnishings evident in Caswell’s private quarters. Everyone knows Dickie Caswell, George had said, lolling indolently on the bed in one of the upstairs rooms. And Dickie knows everyone—and everything. Anything you want to know—for a price.

“Your tact and discretion are most commendable,” Grey said, seeking new footing for a fresh attack. “Why do you say they will not tell me, though?”

“Why, because it isn’t true,” Caswell replied promptly. “They’ve never seen a man called Trevelyan here—how could they tell you anything about him?”
