The dramatic and compelling account of how a serial killer was finally unmasked after evading justice for more than twenty yearsSoon to be a major TV series starring Luke Evans 1980s. In the beautiful, unspoiled landscape of Pembrokeshire, a serial killer is at large: two double murders; an assault; the rape and assault of two teenagers - all potentially the work of one man. This is the fascinating true story of a brutal murderer and the detectives who worked the cold case for six years in order to bring him to justice. Combining cutting edge forensic techniques with old fashioned detective work, a team of detectives worked to build a case against their prime suspect. But it was a race against time: would he strike again? No one could predict that the killer's appearance on the gameshow Bullseye would provide bizarre but crucial evidence. The operation is now recognised as one of the greatest cold case reviews ever undertaken in the UK. The killer is now serving a "life means life" sentence.
