Doc Crawl Down Wall

Doc entered the tenth house quickly. He soon found Long Tom's electrical apparatus which put the high-frequency current on the secret telephone line.

Glancing from the rear window at which he had listened, Doc discovered Long Tom working along the back of the houses with his sensitive electrical "ear" mechanism.

Doc tarried to note that the body of Squint had not been removed from the room. Evidently the other rooms in the house were untenanted.

Then Doc slid through the window, descended the wall as easily as a fly, and consulted with Long Tom.
