He was charming, handsome, and impeccably mannered — a war hero in uniform, a man every woman thought she could trust. But behind Neville Heath’s refined smile lurked one of Britain’s most sadistic killers. In the summer of 1946, two women — Margery Gardner and Doreen Marshall — fell prey to his terrifying double life, victims of a predator who hid behind the mask of a gentleman.

This gripping true-crime documentary unravels Heath’s dark psychology, his deceitful trail across postwar England, and the chilling investigation that exposed his monstrous cruelty. From his manipulative charm to his cold-blooded murders, “Neville Heath: The Lady Killer” explores how evil can wear the face of sophistication — and how one man’s charm became his deadliest weapon.
