Little Boy Blue

ITV, Monday 24 April, 9pm

This four-part drama is based on the tragic real-life case of 11-year-old Rhys Jones, who was murdered in Liverpool in 2007. Made with the full approval of Rhys’ parents, the series will focus on the terrible ordeal they went through, including the fight to put Rhys’ killer behind bars. Sinead Keenan (Being Human) plays mum Melanie, while Brían F. O’byrne (Million Dollar Baby) is dad Steve. Stephen Graham plays SIO Dave Kelly, who led the investigation. A dark, but compelling, piece of TV. Jason Arnopp
