Grace (Seasons 1–6)

Grace (2021) — watch online on iFILM. This ITV crime series is based on the Roy Grace novels by Peter James, with John Simm as the title character: Detective Superintendent Roy Grace of Brighton, a capable officer who has spent so long putting everything into the job that there isn't much left outside it.

His wife Sandy disappeared years ago without explanation. He doesn't officially work the case — but it never leaves him. Alongside that, Grace takes on complex investigations: cold homicides, fresh ones, all handled with methods his superiors keep flagging. Rakie Ayola plays his boss; Craig Parkinson turns up as a rival who makes the politics harder. The procedural detail is tight enough to feel earned.

Peter James's novels have sold over twenty million copies across Europe, and the adaptation captures why: Brighton doubles here as a city of concealed wealth and darker secrets rather than seaside postcards. Stream Grace online on iFILM.
