The murder of Xun Li hits the team hard. This case is more complicated than they first thought, and it's not necessarily connected to the kidnapping. Given there are no indications of forced entry, all early signs point to Xun knowing his murderer. But Xun was also targeting protection gangs and so their boss, the formidable Wendy Xiao, is a prime suspect. And then there's Xun's property rental business – a disgruntled tenant may have an axe to grind.

No-nonsense Yorkshire detective Alan Banks (Stephen Tompkinson) tackles each new case with the weary professionalism of a man who has seen too much. Watch him doggedly decipher the clues in the gruesome murders on his patch.
