"What about this—do you know what this means?" I said.

At sight of the ring, Dauberny turned a greenish white and fell into a chair. Balloquet seized his arm.

"It was I," he said, "who attended the unhappy Annette, the woman you murdered! She is dead; but I received her full confidence, and we are familiar with your crime to its smallest details."

Dauberny could not speak. Great drops of sweat rolled down his forehead; he took a key from his bosom and held it out to us with a trembling hand, stammering almost inaudibly:

"On the second floor. Mignonne is on the second floor."

I motioned to Balloquet to stay with Dauberny, while I flew upstairs to the second floor. I found two doors; the one at the rear was locked. I opened it and found Mignonne on her knees, praying, in a corner of the room. When she heard the door open, she gave a shriek and ran toward the window; but I called her by name; she recognized my voice, and fell unconscious to the floor. Poor girl! joy sometimes kills. I took her in my arms and carried her downstairs. The air revived her; when we reached the yard, she opened her eyes and smiled at me.

"You have saved me again!" she cried.

Balloquet heard our voices and joined us. I told him to take Mignonne to the cab; then I returned to Dauberny, who was still in the lower room, pale and trembling, like a criminal awaiting his doom.

"Monsieur," said I, "we will hold our peace concerning your crime; but you must go away, leave France, and never let your wife see you again."

He motioned that he would obey me, and I made haste to join my friends.
