A veteran medical examiner is found murdered in Commissioner Weston's office. Fingerprints of a knife thrower, who was executed eight years earlier, are found in the room and on the dead body. When the killer strikes again, the same fingerprints are found at the scene. Curious of how a dead man can leave fresh fingerprints at a crime scene, The Shadow investigates.
