Des is due to air on ITV tonight (September 14) and the three-part series stars David Tennant as serial murderer Dennis Nilsen. Nilsen was a serial killer back in the 1980s and he was charged with six counts of murder, and two counts of attempted murder. Fans are keen to find out where Nilsen is now and the cast and crew spoke exclusively to Express.co.uk and other media to explain.
ITV has created a thrilling series which delves into the conviction of Nilsen, and how police dealt with his complex case.
Nilsen spoke openly to police about the men he had murdered at a number of locations after they found body parts in a drain outside his home.
The series starts with the police investigating the scene where the body parts were found, and Nilsen is co-operative with them.
However, when he starts to realise he is becoming a household name, his priorities change and he becomes more manipulative.
The real Nilsen, from Scotland, killed at least 12 victims between 1978 and 1983 in London.

He was sentenced to life imprisonment in 1983, and he was eventually moved to Full Sutton maximum security prison and he died in prison in May 2018.
The murders had been carried out at two addresses - Melrose Avenue and Cranley Gardens.
Speaking about why the series was created, writer Luke Neil said: "Like anyone else, what I knew was was I saw in the documentary.
"I lived quite near where the last three murders had taken place so I started to research it and I realised a lot of things I thought were true were misinformation.
"There was a lot of mistakes about the victims and mistreatment of them and their families because of the prejudice in 1983.
