Originally published in Shadow Magazine, 5/1932. From the back cover:
It was a message from a dead man. A small piece of paper worth a fortune in blood. Eight mysterious symbols that marked the beginning of a chain of violence executed by gangsters willing to kill for a code they did not understand. Only one man called the shots for this riddle: The Chief, whose reputation made any further identification unnecessary – and lethal.
Obviously a case for The Shadow – a cryptic message, a series of baffling murders, seemingly unrelated, and an invisible mastermind who choreographed killings for the highest stakes in town. The Shadow was on a trail leading straight to a brilliant trap – and a face-to-face encounter with a criminal genius determined to beat him at his own game!
