"Dieu! Suzette!" he gasped, staring at her, while she stood upon the threshold, a strange look overspreading her countenance as she recognised him.

"Ah! Look, M'sieur Jacox!" she shrieked a second later. "Yes—yes, it is that man!" she went on, pointing her finger at him. "At last! Thank God! I have found him!"

"What do you mean?" I demanded. "This is M'sieur Pierron."

"I tell you," she cried, "that is the man whom I saw at the Rue de Royat—the man who strangled poor Madame Levitsky!"

"You lie!" he cried, stepping towards her. "I—I've never seen you before!"

He killed the unfortunate woman for two reasons: first, in order to obtain her husband's papers, which had both political and financial importance; and secondly, to obtain her jewellery, which was of very considerable value. And upon me, because I was defenceless, the guilt was placed. They said I was jealous of her."
