He hung up the receiver.

“So you’ve got a pal,” observed Harkness.

“That’s enough out of you,” declared the big man. “We’ve got a lot you’ll find out about if you don’t keep your mouth shut.

“Maybe I’ll get a few more calls if I stick around a while. So we’ll stay here to keep you company.”

Harkness yawned.

“I had hoped we would part company,” he said. “If you don’t want that pad, you might let me have it. The pencil, too.

“I’ll draw you a diagram of how the door works — you may need it.”

The big man handed him the pad and the pencil. Harkness smiled as he received them. He began to sketch. The big man looked suddenly forward.

“Hey!” His voice was filled with anger. “What’re you drawing there?” He snatched the pad away from Richard Harkness. The pencil dropped beside the chair.

The big man ripped the paper from the pad and tore it. He thrust the pieces in his pocket.
