Sogrange smiled.

“You amuse yourself, Mr. Ruff,” he remarked genially.

“Not in the least,” Peter Ruff answered. “I am serious.”

Sogrange watched the blue cigarette smoke come down his nose.

“My dear friend,” he said, “I am no amateur at this game. When I choose to play it, I am not afraid of Scotland Yard. I am not afraid,” he concluded, with a little bow, “even of you!”

“Do you ever bet, Marquis?” Peter Ruff asked.

“Twenty-five thousand francs,” Sogrange said, smiling, “that your efforts to aid Mr. John Dory are unavailing.”

Peter Ruff entered the amount in his pocketbook. “It is a bargain,” he declared. “Our bet, I presume, carries immunity for me?”

“By all means,” Sogrange answered, with a little bow.

The Marquis beckoned to Lord Sotherst, who was crossing the hall.
