He excused himself and stood, moving to the discreetly gesturing servant with calculated insouciance.

Stepping out to the marble-lined hallway, he shut out the noise of his guests with a click of the latch and arched a brow at the courier who waited in the shadows.

"I did as you directed," Thierry said.

"Excellent." The comte smiled.

Thierry extended his hand and in it was an unaddressed missive bearing a black wax seal. Embedded within that seal was a ruby, perfectly round and glimmering in the light of the foyer chandelier. "I was also intercepted a short distance up the street and given this."

Desjardins stilled. "Did you see him?"

"No. The carriage was unmarked and the curtains drawn. He was gloved. I saw nothing more."

The same as always. The first letter had arrived a few months past, always delivered through a passing courier, which led Desjardins to the conclusion that the man had to be a member of the secret du roi. If only he could determine who, and what grievance the man had with Saint-Martin.

Nodding, the comte accepted the note and dismissed Thierry. He moved away from the dining room, heading toward the kitchen, then through it, taking the stairs down to the cellar where he kept his wine. The missive went into his pocket. There would be nothing written within it. After a dozen such communiques he knew that for a certainty.

There would be only a stamp, carved to prevent recognition of handwriting, imprinting one word: L'Esprit. The ruby was a gift for his cooperation, as were the occasional delivered purses of more loose gems. A clever payment, because Desjardins's wife loved jewelry and unset stones were untraceable.

The volume from the bustling kitchen faded to a dull roar as Desjardins closed the cellar door behind him. He rounded the corner of one floor-to-ceiling rack and saw the smaller, rougher wooden planked door that led to the catacombs. It was slightly ajar.
