"Just show Donovan here the receipt I asked you to keep for me."

"All right. I'll get it."

Donovan glanced at the receipt. "Pretty smooth," he muttered.

Waring smiled. His silence enraged Donovan, who motioned to the police
to leave the room.

Waring interrupted. "My gun?" he queried mildly.

One of the police handed the gun to Waring.

Their eyes met. "Why, hello, Pedro!" And Waring's voice expressed
innocent surprise. "When did you enroll as a policeman?"

Donovan was about to interrupt when the policeman spoke: "That is my
business."

"Which means Bill here has had you sworn in to-day. Knew you would like
to get a crack at me, eh? You ought to know better, Salazar."

"Come on!" called Donovan.

The Mexicans followed him down the hallway.

Waring thanked Stanley. "It was a frame-up to get me, Frank," he
concluded. "Pedro Salazar would like the chance, and as a policeman he
could work it. You know that old game--resisting arrest."
