And All That Murder — Joan Merrill

When legendary jazz singer Dee Jefferson asks her friend Casey McKie to investigate the death of a fellow jazz club owner, the San Francisco P.I. hesitates. Though Dee insists it was murder, all the evidence points to suicide. As an African-American, Dee may be simply reacting to her mistrust of the police. And when Casey learns the investigating officer is her ex, she has another reason not to take the job. But friendship wins out, and Casey dives into the case. As more bodies are found, Casey eventually buys Dee's theory that a psychopath is targeting people in the jazz industry. She fears Dee herself may be in the killer's crosshairs. As Casey becomes embroiled in the increasingly complex case, she travels from San Francisco's Chinatown and North Beach to the gay community in Palm Springs to the Pacific Northwest. The quest culminates in a harrowing confrontation with the deadly maniac.
