In the Heat of the Night (Perennial Library Mystery Series)

It's the 1960s. A hot August night lies heavy over the Carolinas. The corpse -- legs sprawled, stomach down on the concrete pavement, arms above the head -- brings the patrol car to a halt. The local police pick up a black stranger named Virgil Tibbs, only to discover that their most likely suspect is a homicide detective from California -- and the racially tense community's single hope in solving a brutal murder that turns up no witnesses, no motives, no clues.
