Suddenly Battle leant forward and touched the chauffeur on the shoulder.
“Stop, will you? And wait for me here.”
He jumped out of the car, much to Anthony’s surprise. But in a minute or two, the latter perceived M. Lemoine advancing to meet the English detective, and gathered that it was a signal from him which had attracted Battle’s attention.
There was a rapid colloquy between them, and then the superintendent returned to the car and jumped in again, biding the chauffeur drive on.
His expression had completely changed.
“They’ve found the revolver,” he said suddenly and curtly.
“What?”
Anthony gazed at him in great surprise.
“Where?”
“In Isaacstein’s suitcase.”
“Oh, impossible!”
“Nothing’s impossible,” said Battle. “I ought to have remembered that.”
He sat perfectly still, tapping his knee with his hand.
“Who found it?”
Battle jerked his head over his shoulder.
“Lemoine. Clever chap. They think no end of him at the Sûreté.”
“But doesn’t this upset all your ideas?”
