As they left the Place de la Concorde, a Frenchman knocked into Illya.
"Excusez-moi, monsieur." The stranger said, steadying the Russian.
"Ne vous inquiétez pas." Illya replied.
Illya and Napoleon continued on their way. Suddely Kuryakin stopped, patting his pockets.
"Chyort, it has gone."
"What?" Napoleon asked.
"The envelope. The man who knocked me must have it."
Turning, they saw their suspect disappear into a building.
"I think we need a chat with our friend. "
"You have a plan?"
"I'm working on one."
Napoleon grinned.
"Go on, I know you want to."
"Someone has lighter fingers than you?"
