THE MAN WHO HID HIS POWERS

THE MARTIAN CONVICT

Detective John Jones is assigned to go undercover in disguise at a penitentiary to learn who is the ringleader of a suspected prison-break plan. Warden Powers tells Jones, disguised as thief Willy Hands, that he knows Big Mike Kent is the main plotter, but does not know who his other main confederates are. Jones confirms Powers's suspicions and learns the identity of the second of three plotters, but his disguise is knocked off accidentally and a convict recognizes him. The Martian survives two attempts to murder him and then discovers the other two ringleaders and turns all three over to Warden Powers.
