Behind the Mask

From the author of Perry Mason, this is the four novelette series of stories starring the private detective Bob Crowder.

ECOND-STORY LAW--He gambled with crime in odd ways, but the strangest was his bet of liberty against a woman's courage and the blindness of the law.

RESTLESS PEARLS--Changing the old adage to "Commit a crime to solve a crime," Bob Crowder made the night a horror and wrote law with dummy bullets.

BEHIND THE MASK--The blaze was meant to be a funeral pyre for Bob Crowder and a girl, but he used it as a finger that marked for death the killer.

THE JACK OF DEATH--Before their very eyes the killer struck again and again, and Bob Crowder, who turned crook to catch crooks, had to wear the glove of murder himself.
