“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.

“Let it go, Dickie,” Grey said, flicking his rapier with a touch of insolence. He lounged a little, looking tolerantly over his glass. “I say I know; you will scarcely convince me I do not. I require only a few small additional details.”

“But—”

“You need not trouble yourself that you will be blamed. If I have learned the main facts about Trevelyan from another source—as indeed I have—then why should I not have learned everything from this same source?”

Caswell had opened his mouth to say something, but instead narrowed his eyes and pursed his mouth in thought.

“Nor do you need to fear that I mean any harm to Mr. Trevelyan. He is about to become a part of my family, after all—perhaps you are aware that he is engaged to my cousin?”

Caswell nodded, almost imperceptibly. His mouth was pursed so tightly that it resembled nothing so much as a dog’s anus, which Grey thought very disagreeable. Still, it scarcely mattered what the evil old creature looked like, so long as he coughed up the necessary details.

“I am sure you will understand that my efforts in this regard are intended solely to protect my family.” Grey glanced away, toward a massive silver epergne filled with hothouse fruit, then back at Caswell. Time for the coup.

“So, then,” he said, spreading his hands with a graceful gesture. “It remains only to decide the price, does it not?”

Caswell made a deep, catarrhal noise, and spat thickly into a new handkerchief, which he then balled up and cast into the fire after its fellows. Grey thought cynically that he must require a good deal of money merely to keep himself in linen.

“The price.” Caswell took a deep swallow of wine and put down the glass, licking his lips. “What do you have to offer? Always assuming that I have something to sell, mind.”

No more pretence of ignorance. The duel was over. Grey could not help a brief sigh, and was surprised to discover that not only were his palms damp but that he was sweating freely beneath his shirt, though the room was not warm.

“I have money—” he began, but Caswell interrupted him.

“Trevelyan gives me money. A lot of money. What else can you offer me?”
