The Reason We Lock Doors

Case two/Dennis Nilsen


Listen Later

mild-mannered civil servant. Two quiet North London flats. Fifteen missing men. And a blocked drain that finally exposed one of Britain's most prolific serial killers.


Join Zoey and Sam as they deep-dive into the chilling case of Dennis Nilsen, known as "The Kindly Killer" and "The Muswell Hill Murderer." We trace the psychological roots of his crimes, from the traumatic loss of his grandfather to the sexual repression and isolation that fueled a five-year killing spree.


Discover the bizarre and grotesque rituals Nilsen performed on his victims, the desperate measures he took to hide the bodies beneath his floorboards and in his garden, and the fateful logistical error—a clogged drain—that ultimately led to his arrest.


More than just a murder story, this episode explores the systemic failures and prejudices that allowed Nilsen to prey on vulnerable young men for years, making this a case about both individual pathology and societal neglect.


⚠️ Content Warning: This episode discusses themes of murder, necrophilia, and sexual violence. Listener discretion is advised.
