The Hunt for Peter Tobin

In 1991, two teenagers disappear without a trace in different parts of the UK. Fifteen years later, the murder of a woman in Glasgow reveals a terrible link between all three cases.

Following Peter Tobin's arrest in connection with the murder of Angelika Kluk, Operation Anagram is launched. The operation tracks down Tobin's ex-wives, and we hear about some of the horrific abuse that Tobin's first wife received at his hands.
