PREVIEW: Fergie's Killer Dresser, ITV

This new documentary in ITV's Crime And Punishment strand explores the case of Jane Andrews, who was the former dresser to Sarah Ferguson, the Duchess of York, and was convicted of murder after police discovered the bloodied body of her millionaire boyfriend Tom Cressman.

Twenty years ago the nation’s front pages were dominated by the story of Andrews, who went on the run after the attack. When she was found and charged, tales soon emerged of her rage at previous boyfriends, earning her the title of the 'Fatal Attraction Killer' after the film of the same name.

Despite her claims of domestic abuse, it took a jury just 12 hours to convict Andrews of Tom’s murder in 2001. She was sentenced to serve a minimum of 12 years of a life sentence.

An appeal against her conviction was quickly dismissed, and as the years passed she lost touch with her society friends. During her sentence Andrews hit headlines again when she absconded from prison for reasons that have never been explained. Then her bizarre love letters to a fellow inmate were published in the press.

Journalists, police, prosecution and Tom Cressman’s friends and family describe their experiences of the extraordinary case, alongside close friends of the killer, and never-seen-before interviews with Jane’s cousin, who has known her since childhood, along with her defence psychiatrist Trevor Turner, who goes on record for the first time.

The film explores whether his claim is right, or if lead investigator Jim Dickie is correct when he says: "She is a cold-blooded murderer. Any man who gets into a relationship with her needs his head tested."
