Episode 2

Part two of the documentary sees detectives close in on Peter Tobin. Following his arrest in connection with the murder of Angelika Kluk, Operation Anagram is launched. This covert investigation into Tobin's past aims to uncover whether he may be connected to other crimes. Overseen by detective superintendent David Swindle, 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. 

A picture develops of a serial domestic abuser who was never charged for his crimes. Sobering archive footage from the period reveals the extensive nature of domestic violence in the pre-1990s UK, which allowed dangerous men to persist within the perceived normality of violence against women. The groundbreaking Zero Tolerance campaign launches in Scotland, bringing the problem of domestic violence out of the shadows. 

In 2007, the murder of Angelika Kluk is a huge news story in Scotland. Salacious claims about her private life are splashed across the front pages, to the dismay of her family. Meanwhile, dogged detective work combined with DNA and fingerprint analysis uncovers dark secrets at Tobin's former residences. We hear from those closest to the story, including reporter Dave Cowan, who was at the scene when the true extent of Tobin's crimes becomes apparent. 

The man leading Operation Anagram, David Swindle, talks of the shock of discovering that Tobin lived in Bathgate in 1991 and that his house was only a few miles from where Vicky Hamilton had last been seen. With Tobin in jail and refusing to answer any questions about his life, the police begin to search his old home in Bathgate and his house in Margate. What would be discovered there would horrify the nation.
