Episode 1

S1, E1: On 9 February 1983, Detective Chief Inspector Peter Jay is called to the leafy North London address of 23 Cranley Gardens, where he discovers the drains clogged with rotting flesh and bones. The extent of this grisly discovery only becomes apparent when the culprit returns from work, as Dennis Nilsen, a meek man, freely admits to the police that it's not just one or two bodies but "15 or 16, I think".
