Armed only with a notepad, pen and mobile phone, author and former Scotland Yard detective and undercover cop, Peter Bleksley is on the hunt for Kevin Parle.

For more than fifteen years, the six-foot six-inch, broadly built, ginger-haired Parle has been wanted by the police for two murders. In the early hours of 19 June 2004, 16 -year-old Liam Kelly was lured to a location in Liverpool and shot dead. The following year, another Liverpudlian, 22-year-old mother of three, Lucy Hargreaves, was shot dead in her own home. Her partner and their 2-year-old daughter escaped after the house was set alight by leaping from a first-floor bedroom window.

How could Parle have evaded national and international crime investigators for so long? Who is harbouring him? Bleksley is determined to find the answers. Immersing himself in the world of serious and organised crime, he has vowed not to rest until Parle is found.

Two murders, one fugitive and a hunter tracking down the target. This is the gripping true story of hunting Britain’s most wanted murderer, and goes behind the scenes of the hit BBC Sounds Podcast, Manhunt: Finding Kevin Parle.
