Des is a new three-part drama series on ITV, and it documents the arrest and conviction of Scottish serial killer Dennis Nilsen. David Tennant takes on the titular character, who murdered a number of young men at his two homes in London. Express.co.uk has everything you need to know about where the series was filmed and set.
Des is based on the true story of Scottish former civil servant Dennis Nilsen, who was also known as The Muswell Hill Murderer.
Nilsen murdered at least 12 men between the years 1978 and 1983 in London, and the series is set during this time period.
Viewers will notice the time period from details such as costumes and the decor inside Nilsen's two homes - in Cranley Gardens and Melrose Avenue, London.
Part of the series is also set at the prison in which Nilsen spent the earlier part of his lifelong sentence - Wormwood Scrubs.

Viewers will also get insight into how the police dealt with the high profile case and the pressures they were under, with Daniel Mays playing DCI Peter Jay.
