Wild Wives by Charles Willeford
Jake Blake is a private detective short on cash when he meets a rich and beautiful young woman looking to escape her father's smothering influence. Unfortunately for Jake, the smothering influence includes two thugs hired to protect her--and the woman is in fact not the daughter of the man she wants to escape, but his wife. Now Jake has two angry thugs and one jealous husband on his case. As Jake becomes more deeply involved with this glamorous and possibly crazy woman, he becomes entangled in a web of deceit, intrigue--and multiple murders. Brilliant, sardonic, and full of surprises, Wild Wives is one wild ride.
