London's best detectives take on its worst crimes in this slick mystery series from the creator of Suspects.

Veteran DI David Bradford (Hugo Speer, Father Brown) heads an elite murder squad, but he's been on leave following the unexplained disappearance of his wife. In his absence, ambitious DS Vivienne Cole (Sharon Small, The Inspector Lynley Mysteries) has been leading the investigations, and when Bradford returns to work, the two clash over their methods and lines of inquiry. Despite the tension, they strive to solve complex crimes, along with DC Rob Brady (Bailey Patrick, Bodyguard) and Trainee DC Billie Fitzgerald (Tori Allen-Martin, Unforgotten).

The only case David can't crack is the one most personal to him - until another of their investigations uncovers evidence linked to his missing wife.
