Showing Miami Blues by Charles Willeford

Ex-con Freddy 'Junior' Frenger lands in Miami with a pocketful of stolen credit cards and plans for a new life of crime, and disappears with a snatched suitcase, leaving the corpse of a Hare Krishna behind him.
Homicide detective Hoke Moseley is soon on his case, chasing the immoral Junior and his hooker girlfriend through the Cuban ghettoes, luxury hotels and seedy suburban sprawl of Miami in an increasingly perilous game of hide and seek.
