When the strangely scarred body of a tramp is discovered in a secluded Amsterdam park, Detective Van Hijn believes this is another victim of a serial killer currently terrorising the city. Discovered on the corpse are contact details for Jon Reed, who can identify the victim as Jake Colby, a stranger he took off the streets and into his London home for a few weeks. Yet it seems that Jon didn't choose Jake - Jake chose Jon. Was Jake really a tramp? And what led him to a life on the streets? What is the connection between the murders and the appearance of alleged Holocaust footage on an illegal internet auction site?
