This is a documntary about one of Britain's lesser known serial kiilers. Although he committed only three murders, Mark Martin is a particularly nasty piece of work. His lifetime's ambition was to become Nottingham's first serial killer, if you can believe that. As Harold Shipman beat him to it, he will have to be satisfied with spilling innocent blood, in particular of three women down on their luck. He also managed to rope in two other men for two of his crimes, one for both of them. This documentary is basically narrative, containing no reconstructions worthy of the name; ignore the psychobabblers and listen in horror.
