Two unsolved double murders from the 1980s cast a shadow over the work of the Dyfed Powys police force.
In 2006, newly promoted Detective Superintendent Steve Wilkins decided to reopen both cases. Employing pioneering forensic methods, Wilkins and his handpicked team found microscopic DNA and fibres that potentially linked the murders to a string of burglaries committed in the 80s and 90s. The perpetrator of those robberies was nearing the end of his prison sentence, but if Steve Wilkins was right, he was also a serial killer... Could Steve and his team find enough forensic evidence to charge their suspect before he was released to potentially kill again?
