He became aware that he was staring at Percy with his mouth open, and closed it. Percy smiled, a little tremulously. The façade of the arrogant, elegant Frenchman had dropped away, and it truly was Percy. His dark curls were hidden under the smooth, powdered wig, but the eyes were as they’d always been—dark, soft, and holding promise. Of various kinds.

“Don’t tell me,” John said, surprised that his own voice sounded normal. “Monsieur Citròn?”

“Yes.”

Percy’s voice was husky, though John couldn’t have said with what emotion. Humor, fear, excitement, lust …? The last thought made him shake off Percy’s grasp and take a step back.

“How bloody long did you know?” he demanded. “Monsieur Citròn” had been his opposite number, in France’s equivalent to the Black Chamber. All countries had one, though the names varied. The underground hive where worker bees gathered the pollen of intelligence, grain by grain, and painstakingly turned it into honey—or poison.

Percy shrugged.

“I’d been working for the Secret du Roi for about two years, before they gave you to me. It took me another six months to discover who you really were.”

Not for the first time, John wished he had Jamie Fraser’s ability to make glottal noises that made clear his state of mind without the nuisance of finding words. But he was an Englishman, and therefore found some.

“Are you working for Hirondelle now?” he demanded. The Secret du Roi—Louis XV’s private spy ring—had not quite perished with the death of the King, but in the manner of such things had quietly been absorbed into a more officially recognized body. He had himself escaped the clutches of Hubert Bowles, head of London’s Black Chamber, some years ago, and had left the world of official secrets behind with the relieved sense of one being fished out of a noisome bog on the end of a rope.

Percy raised one shoulder briefly, smiling.

“If I were still true to La Belle France—and her masters—you couldn’t tell whether I was telling you the truth about that or not, could you?”

John’s heart was beginning to slow down, but that “if” sped it up like a kicked horse. He didn’t reply at once, though. He took time to look Percy up and down, deliberately.

“It’s not quite like leprosy, you know,” Percy said, bearing this scrutiny with visible amusement. “Treason doesn’t show that easily.”

“The devil it doesn’t,” John said, but more for something to say than because it was true. “Are you actually telling me that you have—or are about to,” he added, with a hard look to Percy’s very expensive Parisian finery, “part company with your ‘special interests’ in France?” Including whoever you were working for in the Black Chamber? I wonder.
