Too Long; Didn't Read
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.
