Des is the latest drama from ITV for 2020.
The true-crime series will depict the police investigation into the murders committed by serial killer Dennis Nilsen, who is played by David Tennant.
The story, which details one of the most infamous criminal cases in UK history, is told through the prism of three men, Dennis Nilsen played by Tennant, Detective Chief Inspector Peter Jay played by Daniel Mays and biographer Brian Masters played by Jason Watkins.
ITV's Head of Drama, Polly Hill, said of the series: "This drama starts with Nilsen's arrest and is looking at him through the eyes of the police officer trying to identify those he killed and deliver justice for them and the biographer he chose to tell his story.
"David Tennant is going to be brilliant as Dennis Nilsen and with Daniel Mays as Jay and Jason Watkins as Brian, this has an incredible cast to bring this story to screen and we are delighted to be making this with New Pictures for ITV."
