Simm leads the cast alongside the likes of Richie Campbell (Small Axe) and Rakie Ayola (Shetland).

Read on for everything you need to know about the cast and characters in Grace.

John Simm plays DS Roy Grace

Grace
ITV

Who is DS Roy Grace? Brighton-based Detective Superintendent Roy Grace is a methodical, “hard-working police officer who has given his life to the job”. Several years ago his wife went missing, and since then he appears to have adopted more unorthodox methods in his work, even consulting with a medium (otherwise known as a clairvoyant) in order to track down missing persons.

As a result, he’s essentially been assigned desk duty, but that all changes when his old friend DS Glenn Branson manages to pull him onto a recent, fast-moving missing persons case.

Where have I seen John Simm before? He’s probably best known for playing the Master in Doctor Who, and detective Sam Tyler in the acclaimed Life on Mars. Other projects have included Collateral (as David Mars), Strangers, Trauma, Cold Courage, and The Village alongside Maxine Peake.
