"Oh, no," said Mme. Bernstein, "she is sleeping like an angel."

Did she know her lover was near her, I thought, and that she was saved from the dread peril with which she had been threatened? The mysterious adventure which had led up to the present strange scene in a foreign land warranted such a thought. Little, indeed, do we know of the unseen world by which we are surrounded, little do we understand of the occult influences which direct the most pregnant actions of our lives. Often during the past twenty-four hours had I looked toward the ground in the anticipation of seeing the spectral figure which had prompted every step I had taken in this mystery, but I had seen nothing of it, and I was tempted to believe, its mission being accomplished, that it had left me forever. Though a more fitting place might be found to mention it, I may state here that my impression was correct. From that day to this, when in my London home I am engaged in writing the particulars of the mysterious crime which, through the agency of the supernatural visitation, I was the means of bringing to light, I have never set eyes on the supernatural apparition.

I return now to my companions, who, in the silence of Mr. Nisbet, were debating what it was best to do. If we burst open the door of his bedroom we should awake Beatrice, and the shock might produce serious consequences.

"He may have escaped by the window," suggested Bob.

Rivers shook his head. "He could not do so without breaking his limbs. This floor is some distance from the ground, and a dead straight wall stretches down the back of the house."

"There may be other panels in the walls of his room opening in other directions."

"That is more likely. It is stupid to wait here and do nothing. I have picked a lock before to-night. Here goes."

Down he plumped on his knees, and set to work with his own knife and ours which we handed him. One or another of us held a candle to the keyhole while he worked. It was a long job and a tough job, and he was at it for thirty or forty minutes, but he managed it at last.

"Be prepared for a rush," he said, in a tone of warning, as he slowly pushed the door open.

No such experience awaited us. The door was wide open, and we stood together on the threshold.
