"Come along," exclaimed Harry. "Back to the car. Chefano may be down here any minute."

Bruce glanced over his shoulder as he ran. The ape-faced creature was evidently human. It was clad in old, ill-fitting garments.

Back in the cottage, Bruce talked of their discoveries while Harry tapped a call on the wireless. It was late in the afternoon — time to go through the routine of sending a message, even though there was no hope of a reply.

"The creature is safe inside those bars," said Bruce. "That's why Chefano is keeping it there at present. I figure that he lived in the cabin so as to keep away from the meeting place except on Tuesday nights. But after that trouble in the road, he moved into the old ruins. I don't think he really suspected us of knowing anything. Our trouble with the ape-man was too obviously accidental. He played safe by moving; that's all.

"Did you see those gates in the fence? They were closed and locked with a chain. That must be the entrance to the place. On Tuesday night, the gates will be unlocked."

He ended his comments when Harry Vincent adjusted the ear phones. Both men lighted cigars.

Suddenly, Harry became alert. He listened intently for a minute. Then he sprang to the key.

"At last!" he exclaimed. "A reply!"

With his eyes on the code before him, The Shadow's agent worked with keen rapidity as he sent his report of the new discoveries.
