That same lure was on me now. I heard my voice saying, "Why yes, I guess I'll go, Derek."
CHAPTER III
Into the Unknown
We stood in the boarded room which was Derek's laboratory. Our preparations had been simple: Derek had made them all in advance. There was little left to do. The laboratory was a small room of board walls, board ceiling and floor. Windowless, with a single door opening into the cellar of the apartment house.
Derek had locked the door after us as we entered. He said, "I have sent my man servant away for a week. The people in the house here think I have gone away on a vacation. No one will miss us, Charlie—not for a time, anyway."
No one would miss me, save my employers, and to them I would no doubt be small loss.
We had put out the light in Derek's apartment and locked it carefully after us. This journey! I own that I was trembling, and frightened. Yet a strange eagerness was on me.
The cellar room was comfortably furnished. Rugs were on its floor. Whatever apparatus of a research laboratory had been here was removed now. But the evidence of it remained—Derek's long search for this secret which now he was about to use. A row of board shelves at one side of the room showed where bottles and chemical apparatus had stood. A box of electrical tools and odds and ends of wire still lay discarded in a corner of the room. There was a tank of running water, and gas connections, where no doubt bunsen burners had been.
