“She has dark hair,” Caswell offered helpfully. “Nearly black. Your cousin is fair, I believe?”

Grey didn’t bother answering that.

“And?” he asked tersely.

Caswell pursed his lips, considering.

“She wears considerable paint—but I cannot say, of course, whether that is her normal habit, or part of the guise she adopts when coming here.”

Grey nodded, taking the point. Those mollies who liked to dress as women normally were painted like French noblewomen; a woman hoping to be mistaken for one would likely do the same.

“And?”

“She wears a very expensive scent. Civet, vetiver, and orange, if I am not mistaken.” Caswell cast his eyes up toward the ceiling, considering. “Oh, yes—she has a taste for that German wine I gave you.”

“You said you kept it for a member. Trevelyan, I presume? How do you know it isn’t he alone who drinks it?”

Caswell’s hairy nostrils quivered with amusement.

“A man who drank as much as is brought up to this suite would be incapable for days. And judging from the evidence”—he nodded delicately at the bed—“our Mr. Trevelyan is far from incapable.”

“She arrives by sedan chair?” Grey asked, ignoring the allusion.

“Yes. Different bearers each time, though; if she keeps men of her own, she does not use them when coming here—which argues a high degree of discretion, does it not?”

A lady with a good deal to lose, were the affaire discovered. But the intricacy of Trevelyan’s arrangements was sufficient to tell him that already.

“And that is all I know,” Caswell said, in tones of finality. “Now, as to your part of the bargain, my lord? . . .”

His mind still reeling from the shock of revelation, Grey recalled his promise to Tom Byrd and gathered sufficient wits to ask one more question, pulled almost at random from the swirl of fact and speculation that presently inhabited his cranium.

“All you know about the woman. About Mr. Trevelyan, though—have you ever seen a man with him, a servant? Somewhat taller than myself, lean-faced and dark, with a missing eyetooth on the left side?”

Caswell looked surprised.

“A servant?” He frowned, ransacking his memory. “No. I . . . no, wait. Yes . . . yes, I believe I have seen the man, though I think he has come only once.” He looked up, nodding with decision.

“Yes, that was it; he came to fetch his master, with a note of some kind—some emergency to do with business, I think. I sent him down to the kitchens to wait for Trevelyan—he was comely enough, tooth or no, but I rather thought he was not disposed to such sport as he might encounter abovestairs.”

Tom Byrd would be relieved to hear that expert opinion, Grey thought.

“When was this? Do you recall?”

Caswell’s lips puckered in thought, causing Grey briefly to avert his glance.
