The new TV series, titled Cooper and Fry, will be made up of 4 two-hour episodes, will be set in the Peak District, and will follow two mismatched young detectives.

One of these detectives is Ben Cooper, an affable local who is played by Downton Abbey and The Inheritance star Robert James-Collier. Meanwhile, the other is Diane Fry, a guarded newcomer played by Doctor Who and Curfew star Mandip Gill.

The synopsis for the series says: "Thrown together to investigate a string of mysterious deaths they must learn to work together to get results. As their personal lives begin to intertwine, a unique friendship begins to form... but it won't always be easy."
