Spanning four feature-length episodes, the series draws inspiration from Stephen Booth's bestselling literary works.

Four early novels are being brought to screen: Black Dog, Dying to Sin, Blind To the Bones and Dancing with the Virgins, reports the Express.

Robert James-Collier, recognised for his roles in Downton Abbey and The Inheritance, will star alongside Mandip Gill, celebrated for her appearances in Doctor Who and Suspicion, in the leading roles.

The pair will embody Ben Cooper and Diane Fry, two contrasting young investigators forced to collaborate whilst tackling a series of puzzling fatalities, learning to unite their different approaches to achieve success.

Located in the stunning Peak District, the drama follows Ben and Diane as they develop a "unique friendship" with their personal circumstances becoming increasingly entangled, though the journey "won't always be easy".

Clapperboard produces the series in partnership with STUDIO TF1, who also handle distribution, following a commission from Paul Testar, Commissioning Editor at Channel 5.

Audiences will instantly recognise Robert James-Collier from his roles as the scheming Thomas Barrow in Downton Abbey, the charming Liam Connor in Coronation Street, and the dedicated Martin Evershed in Ackley Bridge.

On the other hand, Mandip Gill is celebrated for her portrayal of Phoebe McQueen in Hollyoaks, the adventurous Yasmin Khan in Doctor Who, and the intriguing Sonia Chopra in Suspicion.

Discussing Channel 5's exciting new ventures, Sebastian Cardwell, Deputy Chief Content Officer and Head of Scripted at Paramount UK, commented: "We're incredibly proud to unveil this new slate of scripted commissions, which showcases the breadth and ambition of 5's storytelling. From brand new thrillers and character-driven mysteries to the much-anticipated return of audience favourites, we're continuing to build a rich and distinctive drama offering."

He added: "These titles reflect our commitment to delivering compelling, accessible British drama that resonates with viewers across the UK. We look forward to announcing further titles in the coming months."
