"Mr. Inspector, I strongly protest against all this farce and against the part which you are unconsciously playing in it. Before your arrival, Prince Rénine told this lady and myself that he knew nothing, that he was venturing into this affair at random and that he was following the first road that offered, trusting to luck. Do you deny it, sir?"

Rénine did not open his lips.

"Answer me, will you? Explain yourself; for, really, you are putting forward the most improbable facts without any proof whatever. It's easy enough to say that I stole the notes. And how were you to know that they were here at all? Who brought them here? Why should the murderer choose this flat to hide them in? It's all so stupid, so illogical and absurd!... Give us your proofs, sir ... one single proof!"

Inspector Morisseau seemed perplexed. He questioned Rénine with a glance. Rénine said:

"Since you want specific details, we will get them from Madame Aubrieux herself. She's on the telephone. Let's go downstairs. We shall know all about it in a minute."

Dutreuil shrugged his shoulders:

"As you please; but what a waste of time!"

He seemed greatly irritated. His long wait at the window, under a blazing sun, had thrown him into a sweat. He went to his bedroom and returned with a bottle of water, of which he took a few sips, afterwards placing the bottle on the window-sill:

"Come along," he said.

Prince Rénine chuckled.
