Sergeant O'Brien #82

In "S.O.S. in Labrador," Sergeant O'Brien investigates the crash of an aircraft carrying a top-secret apparatus destined for a new military base in Labrador. A first-class crew was lost in the crash, but all personnel were accounted for—except the body of the mechanic is missing from the wreckage, and newsreels have been hinting at sabotage. O'Brien pursues a dying airman named Kamo into the frozen Labrador wilderness, where he discovers a mysterious man who appears connected to the disappearance. With Kamo's help, O'Brien pursues the suspect across the snow, determined to uncover the truth behind the crash and the missing mechanic.
