Dead Man's Tunnel: 3 (A Hook Runyon Mystery 3)

Dead Mans Tunnel is the third installment in Sheldon Russells 1940s series featuring yard dog Hook Runyon.. Near the end of WWII Hook Runyon railroad bull and his dog Mixer are sent to the West Salvage Yard in the high desert of Arizona. Not far away is the Johnson Canyon Tunnel. Though remote and ordinary as tunnels go it is the gateway to the steepest railroad grade in North America and a potential bottleneck for the delivery of war supplies. So vital is this tunnel to the war effort that a twenty-four hour military guard has been assigned for the duration. . Hooks orders are to catch copper thieves and to stay out of sight and out of trouble. But things go awry when Hook receives a call that one of the guards has been killed mid-tunnel by an oncoming train. Lieutenant Allison Capron from the Army Transportation Department is called in to help with the investigation. At first suicide by train is suspected but the evidence soon suggests homicide resulting from a love triangle. Unable to fit his own findings into either of these theories Hook suspects something more sinister.
