In the middle-classed neighborhood of Muswell Hill, underneath a spectacular residence located at 23 Cranley Gardens, a gruesome discovery was about to be unearthed. While working on drainage pipes of the house at that location, a plumber discovered several bones and a flesh-like substance covering the inside of the pipes.
The pipes led to the top floor apartment of the residence. It was rented to Dennis Nilsen, a 37-year old, quiet, soft-spoken civil servant. Nilsen was also a retired policeman with military service.
Shockingly, the police were about to discover Dennis Nilsen was also one of Britain's worst serial killers.
