Babs' room! It sent a pang through me. A few of her garments were lying around. A negligee was laid out on the large bed. A velvet boudoir doll—she had always loved them—stood on the dresser. Upon this Hotel room, in one day, she had impressed her personality. Her perfume was in the air. And now she was gone.

"We won't be here," Alan was repeating. He gripped me at the window. "Look." In his hand was an ugly-looking, smokeless, soundless automatic of the Essen type. "And I've got another one for you. Brought them with me."

His face was white and drawn, but his hands had steadied. The tremble was gone out of his voice.

"I'm going after him, George! Now! Understand that? Now? His place is only thirty miles from here, out there in the mountains. You can see it in the daylight—a wall around his property and a stone castle which he built in the middle of it. A gold mine? Hell!"

There was nothing to be seen now out of the window but the snow-filled darkness, the blurred lights of Lower Quebec and the line of dock lights five hundred feet below us.

"Will you fly me, George?"

"Of course."

I was the one trembling now; the cool feel of the automatic which Alan thrust into my hand seemed suddenly to crystallize Babs' peril. I was here in her room, with the scent of her perfume around me, and this deadly weapon was needed! But the trembling was gone in a moment.

"Yes, of course, Alan. No use talking to the police. I gave them all the information—a description of her, what you said she was wearing. No sense dragging Polter's name into it, with nothing tangible to go on. The police won't ransack the castle of a rich man just because you can't find your sister. Come on. You can tell me what this place is like as we go."
