The Thirteenth Trick — Russell Braddon

Russell Braddon opens this novel of character and suspense with a murder as viewed by the victim herself. Then the body is found in the back row of a rural English cinema, and it appears that the murderer who victimizes only young, blond female hitchhikers has struck for the fourth time in a year. The question unresolved until the very last pages is: Who is the target of the investigation?
