The premise
The story of one of the most infamous cases in UK criminal history, that of serial killer Dennis Nilsen. Told through the prism of three men, the series explores the personal and professional consequences of coming into contact with a man like Nilsen.
Horror Vault's take
Based on the real-life case of one of Britain's most notorious serial killers, this three-part drama follows the investigation into Dennis Nilsen and its profound impact on those drawn into his orbit. David Tennant delivers a chilling central performance that prioritises psychological unease over cheap shock value. Rather than sensationalising the crimes, the series examines the ripple effects on detectives, survivors, and the justice system itself — asking difficult questions about how such evil goes undetected for so long.
