“ Mais oui , Monsieur. Two apaches set upon an elderly American gentleman.”

“They did him no injury?”

“No, indeed.” The man laughed. “The American, he had a revolver in his pocket, and before they could attack him, he fired shots so closely round them that they took alarm and fled. The police, as usual, arrived too late.”

“Ah!” said the inquirer.

He displayed no emotion of any kind.

Placidly and unconcernedly he resumed his nocturnal strolling. Presently he crossed the Seine and came into the richer areas of the city. It was some twenty minutes later that he came to a stop before a certain house in a quiet but aristocratic thoroughfare.
