I was at the door, behind the intruder, and when, next moment, I switched on the light, to my astonishment I found myself confronted with Lola Sorel!

"You!" I gasped, as the girl shrank from me against the wall, her face white as death. "You—Mademoiselle! What is the meaning of this visit—eh?"

"Will you—will you close the door, M'sieur?" she begged in a low whisper, in broken English. "Some one may overhear."

I did as she bade, and slipped on my dressing-gown, which was hanging over the foot-rail of the bed.

"Well?" I asked, with a good deal of severity, for I saw by her manner that she was there for some nefarious purpose. She was dressed in plain black, with a neat little velvet cap, and wore slippers with rubber soles. Her hands were covered with india-rubber gloves, such as surgeons often wear when operating or making post-mortem examinations. Her electric torch was attached to her wrist, while, beneath her dark golf-coat, which fell open, I saw that she wore around her waist a capacious bag of black silk.

"I—I never dreamed that this was your room, M'sieur," the girl declared, terrified. "I—I——"

But she did not conclude her sentence, for she realized how completely she had been trapped. Her pretty countenance betrayed terror in every line, her eyes were staring and haggard, and her hands were trembling.

"I—I—know there is no escape," she said with her pleasing French accent. "You are aware of the truth, M'sieur—of what occurred in Copenhagen. Ah, yes. It is Fate that you and I should again meet—and in these circumstances."

"Please be seated, Mademoiselle," I said. "You have no cause for alarm. Naturally, this encounter has upset you."

I feared that she might faint, therefore I went to the table where, on the previous night, the valet had placed some brandy and a siphon of soda. Mixing a little, I gave it to her to drink.
