ITV’s Grace cast

John Simm (Doctor Who, Life on Mars) plays the titular Brighton-based Detective Superintendent Roy Grace, a “hard-working police officer who has given his life to the job”.

Joining him are Richie Campbell (Liar, Top Boy) who plays DS Glenn Branson and Rakie Ayola (Noughts + Crosses) as ACC Vosper.

Other cast members include Laura Elphinstone (Game of Thrones) is DS Bella Moy, Amaka Okafor (The Split, Vera) plays DC Emma Jane Boutwood, and Brad Morrison takes the role of DC Nicholl.

What is ITV’s Grace about?

The two-part drama (each episode lasting two hours) is adapted from the first two books in the Roy Grace series: Dead Simple and Looking Good Dead.

According to the ITV synopsis, the first film, Dead Simple, sees Grace “fixated by the disappearance of his beloved wife, Sandy, which haunts his thoughts. His unorthodox police methods have come under scrutiny once again and Grace is walking a career tightrope and risks being moved from the job he loves most.”

Writer Russell Lewis said he was “thrilled and honoured to be involved in bringing Peter James’ brilliantly gripping series of Roy Grace novels to ITV”.

He continued, “Each story is a fantastic, hair-raising, twisting, switch-back of a roller-coaster ride that grips the reader from first to last, and the opportunity to translate that best-selling magic to television is like all one’s Christmases and birthdays come at once.  As his millions of fans and admirers are well aware, Peter’s meticulous research and eye for detail is the stuff of legend.

“His long established, close relationship with the police, taken together with a knowledge of Brighton and the South Coast that is the sole preserve of the born and bred lends his stories an unimpeachable veracity of place and procedure.  That John Simm will be breathing flesh to the bones of Roy Grace really is the cherry on a dark, and troublingly encrimsoned cake…”
