Harry could hear the man approaching through the darkness. Breathlessly he waited. The person was now close to him. He could hear the man fumbling among the shelves, not more than a yard away.
Then came silence. Harry waited for fully five minutes. Then he turned on his flashlight. He was alone!
This second occurrence of the mystery was annoying. Harry knew now that some secret lay in this place. He examined the shelves carefully, but found nothing.
How had the man disappeared?
Who was it?
Could it be The Shadow?
Harry felt that it was inadvisable to stay in the cellar, now that he had missed his opportunity. He went upstairs. Peering around a corner, he saw Bert Crull still reading in the living room.
Harry now suspected Perry Quinn; and this bore out his suspicions, unless — as he had conjectured before — The Shadow had entered the game.
Harry entered the living room. Crull looked up in surprise.
“Thought you had gone to bed,” he remarked.
