This true story about the murder of 11-year-old Rhys Jones in Liverpool 10 years ago really picks up the pace tonight as the investigation to find the killer gathers momentum.

It’s an incredibly well-balanced episode that switches between the devastation of Rhys’s family, the urgency of the police and the reign of terror by the gang members responsible for the shooting.

The police pretty much know who did it, but they have to prove it and with no one wanting to be labelled a grass, that is proving a difficult task.

Considering the hideousness of the murder of a child, it’s a clever script that can make you feel for some of the young men, and their families, involved in Rhys’s killing.
