"It may have been he who thrust the paper under our door before—before the fire?" ventured Jack.

"It was," nodded Mlle. Nadiboff, seriously. "And it was the same waiter who, on receiving this envelope from me, would have mixed the contents with the next cup of coffee served you in the dining room of this hotel. But I am overcome by your generosity, my Captain. Take this envelope—and do not place what it contains in your coffee."

Though Jack Benson may have started inwardly, his hand did not tremble in the least as he reached out and took the envelope, which he dropped into one of his pockets.

"Thank you, Mademoiselle," he said, simply.

"There is nothing about me, my Captain, that you can admire," spoke the Russian woman, sadly. "I have not led the right kind of life. But I have just that grain of good in me that enables me to admire one as fine and manly as I have found you to be. You have given me my life—a worthless one, at best. So I give you your life—and may you make as splendid use of it as you have started out to do. And now, good-bye, my Captain. You cannot continue to know such as I."

Despite what he knew of this dangerous woman, Jack Benson felt himself touched.

"What is going to become of you, Mademoiselle?" he asked. "Will you be dragged down in the snares that have entrapped your confederates!"

"I do not know. How could I know?" she asked, looking quickly up at him. "Yet, if my accomplices escape, and find that I have served you, my Captain, do you know the forfeit they will exact?"

"Your life?" whispered Benson.

"Yes!"
