That made sense; while O’Connell might have gathered useful military information in the field, he would have found it infinitely easier to pass it on in the seething anthill of London—where men of every nation on earth mingled daily in the streams of commerce that flowed up the Thames—than in the shoulder-rubbing confines of a military camp.

“Oh, I see,” Grey said, shooting a sharp glance at Quarry as the light dawned. “Hal took advantage of the gossip regarding the regimental posting, didn’t he? Stubbs told me after luncheon that he’d heard from DeVries that we were definitely set for France again—likely Calais. I take it that was misdirection, for O’Connell’s benefit?”

Quarry regarded him blandly. “Wasn’t announced officially, was it?”

“No. And we take it that the coincidence of such an unofficial decision and the sudden demise of Sergeant O’Connell is sufficient to be . . . interesting?”

“Depends on your tastes, I s’pose,” Quarry said, heaving a deep sigh. “Damn nuisance, I call it.”

The servant came quietly back into the room, bearing a humidor in one hand, a rack of pipes in the other. The supper hour was drawing to a close, and those members who liked a smoke to settle their digestions would be coming down the hallway shortly, each to claim his own pipe and his preferred chair.

Grey sat frowning for a moment.

“Why was . . . the gentleman in question . . . suspected?”

“Can’t tell you that.” Quarry lifted one shoulder, leaving it unclear as to whether his reticence was a matter of ignorance or of official discretion.

“I see. So perhaps my brother is in France—and perhaps he isn’t?”

A slight smile twitched the white scar on Quarry’s cheek.

“You’d know better than I would, Grey.”

The servant had gone out again, to fetch the other humidors; several members kept their personal blends of tobacco and snuff at the club. He could already hear the stir from the dining room, of scraping chairs and postprandial conversation. Grey leaned forward, ready to rise.

“But you had him followed, of course—O’Connell. Someone must have kept a close eye on him in London.”

“Oh, yes.” Quarry shook himself into rough order, brushing ash from the knees of his breeches and pulling down his rumpled waistcoat. “Hal found a man. Very discreet, well-placed. A footman employed by a friend of the family—your family, that is.”

“And that friend would be . . .”

“The Honorable Joseph Trevelyan.” Heaving himself to his feet, Quarry led the way out of the smoking room, leaving Grey to follow as he might, senses reeling from more than tobacco smoke.
