“He could be either banished or executed, thus leaving you a good deal more freedom with regard to his wife. Quite.”

Trevelyan glanced sharply at him, but chose not to take issue with his tone.

“Quite,” he said, matching Grey’s irony. “It was, however, a delicate matter to arrange things so that O’Connell and Mayrhofer should be brought together. O’Connell was a wary blackguard; he’d waited a long time to search out a buyer, and was highly suspicious of any overtures.”

Trevelyan, restless, got up and moved back to the bed.

“I was obliged to see O’Connell myself, posing as a putative middleman, in order to draw the Sergeant in and assure him that there was money available—but I went disguised, and gave him a false name, of course. Meanwhile, though, I had succeeded from the other end, in interesting Mayrhofer in the matter. He decided to cut me out—duplicitous bastard that he was!—and set one of his own servants to find O’Connell.”

Hearing Mayrhofer’s name from another source, and realizing that the man he spoke to was acting under an assumed identity, O’Connell had rather logically deduced that Trevelyan was Mayrhofer, negotiating incognito in hopes of keeping down the price. He therefore followed Trevelyan from the place of their last meeting—and tracked him with patience and skill to Lavender House.

Discerning the nature of the place from questions in the neighborhood, O’Connell had thought himself possessed of a marked advantage over the man he assumed to be Mayrhofer. He could confront the man at the scene of his presumed crimes, and then demand what he liked, without necessarily giving up anything in return.

He had, of course, been thwarted in this scheme when he found no one at Lavender House who had heard the name Mayrhofer. Baffled but persistent, O’Connell had hung about long enough to see Trevelyan depart, and had followed him back to the brothel in Meacham Street.

“I should never have gone directly to Lavender House,” Trevelyan admitted with a shrug. “But the business with O’Connell had taken longer than I thought—and I was in a hurry.” The Cornishman could not keep his eyes from the woman. Even from where he sat, Grey could see the flush of fever rising in her pallid cheeks.

“Normally, you would have gone to the brothel first, thence to Lavender House, and back again, in your disguise?” Grey asked.

“Yes. That was our usual arrangement. No one questions a gentleman’s going to a bordello—or a whore coming out of one, being taken to meet a customer.” Trevelyan said. “But Maria naturally could not meet me there. At the same time, no one would suspect a woman of entering Lavender House—no one who knew what sort of place it is.”

“An ingenious solution,” Grey said, with thinly veiled sarcasm. “One thing—why did you always employ a green velvet dress? Or dresses, as the case may be? Did you and Mrs. Mayrhofer both employ that disguise?”

Trevelyan looked uncomprehending for a moment, but then smiled.
