If you're looking for your next gripping TV fix, this could be it.

ITV's new true-crime drama Des sees David Tenant portray serial killer Dennis Nilsen.

The three-part series will depict the police investigation into the murders committed by the notorious necrophile.

Nilsen is believed to have killed up to 15 people after he confessed to police back in 1983.

But even to this day, not all the bodies have been recovered.

Des is based on material from the book Killing For Company by Brian Masters which focuses on one of the most infamous cases in UK criminal history.

The story will be 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.

The series will explore the personal and professional consequences of coming into contact with a man like Nilsen.

It will air over three consecutive nights from Monday, September 14, at 9pm on ITV.

ITV's Head of Drama Polly Hill has said: "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."
