A door opened, and the man went out of sight. Harry followed. The door led to the cellar stairs. Harry could hear the man’s footsteps, although they were very light.
Evidently the person who was moving into the darkness below felt sure that he was not being followed, yet he was going cautiously.
Harry proceeded with absolute stealth. He reached the stone-floored cellar, and followed noiselessly, trailing the man by the slight sounds that came from ahead.
Who was it?
Harry could not tell. The only persons whom he could positively eliminate were Blair Windsor and Garret Buckman, who were on the veranda.
It might be Perry Quinn, come in from outside when he saw the others go to the porch. It might be Bert Crull, who had been in the living room.
Harry Vincent was determined to learn the identity of this individual.

They were across the cellar now. Harry had never been in the place before. He was in constant danger of running into a post, or of stumbling over something which might betray his presence. Yet the man ahead seemed to know the path perfectly.
Harry came to a halt. He stood stock-still, for he could hear the other man breathing. They must be very close, and near the far wall of the cellar; for the man in the dark was no longer in motion.
