Episode 16: Serial Killer Dennis Nilsen

On November 23, 1945, a man by the name of Dennis Andrew Nilsen was born. He grew up in Fraserburgh, Aberdeenshire. His childhood was filled with love and comfort but after the death of his grandfather in 1951, things started to change within Dennis. He grew more reclusive and didn't spend much time with friends or family. Eventually he would start having fantasies that at first involved an unconscious partner, but then quickly escalated to involving a dead partner.

Between 1978 and 1983, Dennis would attempt to bring those fantasies to life. What atrocious things would Dennis do and how would anyone stop him?
