"If it amuses you," said Sernine.

And, picking out Doudeville in the front row of his assailants, he put out his wrists:

"There, my friend, you shall have the honour . . . and don't trouble to exert yourself. . . . I'm playing square . . . as it's no use doing anything else. . . ."

He said this in a tone that gave Doudeville to understand that the struggle was finished for the moment and that there was nothing to do but submit.

Doudeville fastened the handcuffs.

Without moving his lips or contracting a muscle of his face, Sernine whispered:

"27, Rue de Rivoli . . . Geneviève. . . ."

M. Weber could not suppress a movement of satisfaction at the sight:

"Come along!" he said. "To the detective-office!"

"That's it, to the detective-office!" cried Sernine. "M. Lenormand will enter Arsène Lupin in the jail-book; and Arsène Lupin will enter Prince Sernine."
