Adapted by Endeavour writer Russell Lewis from Dead Simple, the first novel in bestselling author Peter James’ Roy Grace series of thrillers, is stars John Simm as the eponymous Brighton-based detective – a man who is as dedicated to his job as he is unorthodox.

“Do we want pepperoni on that?”

Grace is haunted by the disappearance of his wife, and his career has hit a wall. Tasked with following up leads on cold cases, he runs the risk of being moved from his job after rubbing his superiors up the wrong way yet again. That’s until Detective Sergeant Glenn Branson (Richie Campbell, Liar) asks Grace to help him on a mysterious new case.

When a groom goes missing following his stag night, Grace and Branson get to work on figuring out where he is and what has happened to him. But as the detective duo try to locate their man, who boasts a successful career as a property developer, Grace finds himself dangerously drawn to the bride-to-be.

With another feature-length episode due to air later this year, Grace is the latest crime drama from ITV that looks set to have viewers hooked from start to finish. Here, star John Simm explains more about this new thriller…
