The police investigate the murder of a former professional footballer, Robert Nichols, who is found lying beside his car bludgeoned to death. He was on his way to meet his sister and was apparently replacing a flat tire when the attack occurred. The only thing taken was his very expensive watch. They manage to trace a passerby, Mike Jones, who initially denies having seen anything but eventually admits he was helping Nichols fix his flat. The police are naturally suspicious and believe Jones may have been the perpetrator. In checking into Nichols's background however, they learn he was a big-time gambler and owed well-known mobster Don Marsh a quarter of a million pounds. Jones obviously has good reason to lie since he saw who killed Nichols but the mobster has made it clear that his life is in danger if he testifies.

DS Devlin and DS Brooks investigate the murder of a 13 year-old boy boy, Sean Monroe, the son of a fellow police officer who was killed and put down a storm drain. A note found on the body points to the work of Andrew Dillon, who was sentenced for an earlier racial murder and is serving his sentence. The racial motivation for the killing seems confirmed when a second boy, Dev Desai, is found strangled with the same note in his pocket. However, their investigation leads to a security guard, Marcus Wright, who admits to having encounters with both boys at the shops where he works. He says the boys deaths were God's will and he was simply doing God's work. If Wright is to be believed, it means that Dillon was wrongfully convicted. The case becomes personal when James Steel is accused of having purposely buried a witness statement that would have likely exonerated Dillon. He finds himself in dock but the judge allows him to conduct his own defense.
