“You don’t look a day over a thousand, Mother Caswell,” Grey said lightly. That was the truth, too; beneath his modish bag-wig and an extravagant suit of striped blue silk, the man might as well have been an Egyptian mummy. Bony brown wrists and hands like bundles of dry sticks protruded from the sleeves; while the suit had undoubtedly been made by an excellent tailor, it hung upon his shrunken form like a scarecrow’s burlap.

“You shameless flatterer.” Caswell looked him over, amusement flickering in his eyes. “Can’t say the same for you, my dear. You look as fresh and innocent as the day I first saw you. How old were you then, eighteen?” Caswell’s eyes were just the same; small, black, and clever, perpetually bloodshot from smoke and late hours, sunk in pouches of deep violet.

“I lead a wholesome life. Keeps the skin clear.”

Caswell laughed, then began to cough. With a practiced economy of motion, he drew a crumpled handkerchief from his waistcoat and clapped it to his mouth. He lifted a sketchy brow at Grey, half-shrugging as though to apologize for the delay of their conversation, meanwhile suffering the racking spasms with the indifference of long custom.

The coughing done at last, he inspected the resultant blood spots on the handkerchief and, evidently finding them no worse than expected, tossed the cloth into the fire.

“I need a drink,” he said hoarsely, rising from his chair and heading toward the big mahogany desk, where a silver tray held a decanter and several glasses.

Unlike Magda’s sanctum, Caswell’s room held nothing at all that indicated the nature of Lavender House or of its members; it might have belonged to a director of the Bank of London, for all its soberness and elegance of furnishing.

“You’re not enjoying that swill, are you?” Caswell nodded toward the discarded glass of porter. He filled a pair of crystal wineglasses with a deep crimson liquid, and held one out. “Here, have some of this.”

Grey took the proffered glass with a sense of unreality; he had taken wine here, in this room, when George had first brought him to Lavender House—a prelude to their retiring to one of the chambers upstairs. The sense of mild disorientation was succeeded by a sharp shock when he took the first sip.

“That’s very good,” he said, holding the glass up to the fire as though to appraise the color. “What is it?”

“Don’t know the name,” Caswell said, sniffing at the wine with appreciation. “German stuff, not bad. Had it before?”

Grey closed his eyes and drank deeply, frowning and affecting to wash it about his tongue in an effort at placement. Not that he entertained the slightest doubt. He had a good nose for wine, and a better palate—and he had drunk enough of this particular vintage with Nessie to be more than sure of recognizing it again.

“Might have,” he said, opening his eyes and meeting Caswell’s penetrating gaze with an innocent blink. “Can’t recall. Decent stuff, though. Where’d you find it?”

“One of our members prefers it. He brings it by the cask, and we keep it in the cellar for him. Fond of it myself.” Caswell took another sip, then set down his glass. “Well . . . my lord. How might I have the pleasure of serving you?” The fleshless lips rose in a smile. “Do you mean to seek membership in the Lavender Club? I’m sure the committee would look upon your application with the most cordial favor.”

“Was that the committee I met in the library?” Grey asked dryly.

“Some of them.” Caswell uttered a short laugh, but choked it off, unwilling to start another coughing fit. “Mind you, they might require you to submit to a series of personal interviews, but I’m sure you would have no objection to that?”

The glass felt slippery in his hand. He’d once seen a young man bent over a leather ottoman in that library and subjected to a number of personal interviews, to the vast entertainment of all present. They still had the ottoman; he’d noticed.

“I am exceedingly flattered at the suggestion,” he said politely. “As it happens, though, what I require at the moment is information, rather than companionship, delightful as that prospect might be.”

Caswell coughed, sitting up a little straighter. The smile was still there, but the black eyes had grown brighter.

“Yes?” he said. Grey could almost hear the whisper of steel drawn from a scabbard. The pourparlerswere done; let the duel begin.

“The Honorable Mr. Trevelyan,” he said, laying his own blade against Caswell’s. “He comes here regularly; I know that already. I wish to know whom he meets.”

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?”

“Not a man, no. I rather imagine they have seen him as a woman.”

He felt a small rush of exhilaration, seeing the violet swags under Caswell’s eyes deepen in hue as the color paled from his cheeks. First blood; he’d pinked his man.

“In a green velvet gown,” he added, pressing the advantage. “I told you—I know he comes here; the fact is not in question.”

“You are quite mistaken,” Caswell said, but a cough bubbling to the surface gave the words a quavering aspect.
