Juve had spoken in a tone of command that brooked no reply. His keen eyes seemed to pierce through Paul and read his inmost soul. The winking light of the street lamp shed a wan halo round the lad, who obviously wanted to move away from its radius, but Juve held him fast.

"Come now, answer! You are Charles Rambert, and you were Mademoiselle Jeanne?"

"I don't understand," Paul declared.

"Really!" sneered Juve. He hailed a passing cab. "Get in," he ordered briefly, and pushing the lad in before him he gave an address to the driver, entered the cab and shut the door. Juve sat there rubbing his hands as if well pleased with his night's work. For several minutes he remained silent, and then turned to his companion.

"You think it is clever to deny it," he remarked, "but do you imagine it isn't obvious to anyone that you are Charles Rambert, and that you were disguised as Mademoiselle Jeanne?"

"But you are wrong," Paul insisted. "Charles Rambert is dead."

"So you know that, do you? Then you admit that you know whom I am talking about?"

The lad coloured and began to tremble. Juve looked out of the window, pretending not to notice him, and smiled gently. Then he went on in a friendly tone. "But you know it's stupid to deny what can't be denied. Besides, you should remember that if I know you are Charles Rambert I must know something else as well; and therefore——"

"Well, yes," Paul acknowledged, "I am Charles Rambert, and I was disguised as Mademoiselle Jeanne. How did you know it? Why were you at the Saint-Anthony's Pig? Had you come to arrest me? And where are you taking me now—to prison?"

Juve shrugged his shoulders.
