Electra Glide in Blue

John Wintergreen is a motorcycle cop who patrols the rural Arizona highways with his partner Zipper. Wintergreen is an experienced patrolman looking to be transferred to the Homicide unit. When he is informed by Crazy Willie of an apparent suicide via shotgun, Wintergreen believes the case is actually a murder as the victim has shot himself in the chest rather than the head, which is more usual. Detective Harve Poole agrees it is a homicide, after a .22 bullet is found amongst the pellets in the man's chest during the autopsy, as well as hearing about a possible missing $5,000 ($ today) from the man's home, and arranges for Wintergreen to be transferred to homicide to help with the case.
