Grace is a British television crime drama series, based in the English city of Brighton and Hove, that stars John Simm in the title role of Detective Superintendent Roy Grace, a dogged detective who, haunted by the disappearance of his wife some years previously, solves a variety of cases.^[1]

The series, based on the bestselling novels by novelist Peter James,^[2] was adapted by acclaimed screenwriter Russell Lewis, with a pair of films, comprising the novels Dead Simple and Looking Good Dead, filmed in 2020 for broadcast in 2021.^{[3][failed verification]} "Dead Simple", broadcast in March 2021, attracted an estimated 7.2m viewers, which made it the fifth-most-watched programme for the week of 8–14 March, according to BARB.^[4]

Following strong viewing figures for the opening episode, a second series of three films was then commissioned in 2021, with broadcasting beginning in May 2022.^[5] A third series was subsequently commissioned in 2022, with filming beginning in August 2022 and broadcasting starting in March 2023.^[6]

The first series was predominantly filmed in Brighton and Hove; however, location filming also took place in Sussex,^[7] particularly around the border between East and West Sussex.^[8] The first episode, Dead Simple, was shifted forward in the schedules by a week, originally set to air on 21 March.^[9] This was to avoid a clash with the launch of the sixth series of the BBC's Line of Duty. Subsequently, this led to the decision to postpone Looking Good Dead until a later date.^[10][11][12] Subsequently, when the first series aired in the United States, it meant that "Looking Good Dead" was available to stream for more than a year before its British broadcast.

In May 2021, Grace was commissioned for a second series. Filming began in September 2021 in the West Sussex town of Burgess Hill. The second series adapts the next three novels in the Grace series, Not Dead Enough, Dead Man's Footsteps and Dead Tomorrow. Broadcasting of the second series commenced in the UK on 24 April 2022, with "Looking Good Dead" as the opening episode.^[13]

A third series was subsequently commissioned in May 2022, adapted from the novels Dead Like You, Dead Man's Grip and Not Dead Yet. For this series, Russell Lewis stepped down as showrunner and principal writer, with former Whitechapel writers Ben Court & Caroline Ip penning two episodes, and prolific screenwriter Ed Whitmore penning the other. The series also features Sam Hoare as a new ACC, following the departure of Rakie Ayola at the end of series two.^[14]

In April 2023, Simm confirmed via Instagram that Grace would return for a fourth series with four episodes in 2024.
