"By what right did those people dare to attack the most blameless of women? I killed only one man that day! I would have killed ten! I would have killed twenty! What was Chief Inspector Ancenis's life to me? What cared I for the lives of any of those wretches? They stood between Marie and myself; and Marie was in prison!"

Gaston Sauverand made an effort which contracted every muscle of his face to recover the coolness that was gradually leaving him. He succeeded in doing so, but his voice, nevertheless, remained tremulous, and the fever with which he was consumed shook his frame in a manner which he was unable to conceal.

He continued:

"At the corner of the street down which I turned after outdistancing the Prefect's men on the Boulevard Richard-Wallace, Florence saved me just as I believed that all was lost. Florence had known everything for a fortnight past. She learnt the news of the double murder from the papers, those papers which she used to read out to you, and which you discussed with her. And it was by being with you, by listening to you, that she acquired the opinion which everything that happened tended to confirm: the opinion that Marie's enemy, her only enemy, was yourself."

"But why? Why?"

"Because she saw you at work," exclaimed Sauverand, "because it was more to your interest than to that of any one else that first Marie and then I should not come between you and the Mornington inheritance, and lastly—"

"What?"

Gaston Sauverand hesitated and then said, plainly:

"Lastly, because she knew your real name beyond a doubt, and because she felt that Arsène Lupin was capable of anything."

They were both silent; and their silence, at such a moment, was impressive to a degree. Florence remained impassive under Don Luis Perenna's gaze; and he was unable to discern on her sealed face any of the feelings with which she must needs be stirred.
