Doc See Wire

Doc was facing the window again, apparently lost in thought. Actually, while standing there a moment before, he had felt vaguely that something was out of place about the window.

Then he got it! The mortar at one end of the granite slab which formed the window sill was fresher than on the other side. The strip of mortar was no wider than a pencil mark, yet Doc noticed it. He leaned out the window.

A fine wire, escaping from the room through the mortared crack, ran downward! It entered a window below.

Doc flashed back into the room. His supple, sensitive, but steel-strong hands explored. He brought to light a tiny microphone of the type radio announcers call lapel mikes.

"Somebody has been listening." His powerful voice throbbed through the room. "In the room below! Let's look into that!"
