Bad Penny Blues is the latest gripping crime fiction from Cathi Unsworth, London's undisputed queen of noir. Set in late 1950s and early 1960s London, it is loosely based on the West London “Jack the Stripper” killings that rocked the city. The narrative follows police officer Pete Bradley, who investigates the serial killings of a series of prostitutes, and, in a parallel story, Stella, part of the art and fashion worlds of 1960s “Swinging London,” who is haunted by visions of the murdered women.
