Grace Season 4: Release Date Set for 2024 on ITV1

A shocking attack on the Brighton music scene and a gruesome discovery on a Sussex pig farm force Grace to split his team to solve the two mysteries.

Grace and his team are called to the site of a tragic road traffic collision involving three vehicles: an articulated lorry, a car and a blue pickup truck. An unexpected discovery at the scene, found on the victim, soon suggests there could be far more to this particular accident than meets the eye, sparking an unsettling chain of events which leads Grace and Branson on a tense, desperate game of cat and mouse through the city of Brighton to save an innocent life before time runs out.

A chilling event at the Royal Edward hotel on the night of Assistant Chief Constable, Alison Vosper's leaving do forces Grace and Branson into a difficult position when they must investigate all hotel guests, including high ranking East Sussex police attendees.

Something about the incident is causing a deep unease in Grace - he knows he's seen this before. Has a sinister offender from Grace's past dubbed the Brighton Prowler resurfaced or is this a copycat?

As the attacks continue, Grace is convinced it's the same man - and delving into the past may be the key to saving the next victim.

A body is dredged up from the English Channel, setting in motion a truly disturbing investigation that forces Detective Superintendent Roy Grace to ask himself just how far someone might go to save the ones they love.

A sinister inquiry into skeletal remains found in a Brighton storm drain takes Grace down a labyrinthine trail through the past, but it's not only on the professional front that he is chasing ghosts.

Branson and Grace investigate the murder of socialite and patron of local charities Katya Bishop, whose entrepreneur husband Kit becomes the main suspect. The Bishops seem to have led a charmed life, until Grace digs deeper behind the respectable facade and discovers all is not what it seems. Doing so, however, places him unknowingly in grave danger.

Tom Bryce did what any decent person would do. But within hours of picking up the memorystick that had been left behind on the train seat next him, and attempting to return it to its owner, he is the sole witness to a vicious murder. Then his young family are threatened with their lives if he goes to the police. But supported by his wife, Kellie, he bravely makes a statement, to the murder enquiry team headed by Detective Superintendent Roy Grace, a man with demons of his own - including his missing wife - to contend with. And from that moment, the killing of the Bryce family becomes a mere formality - and a grisly attraction. Kellie and Tom's deaths have already been posted on the internet. You can log on and see them on a website.

Detective Superintendent Roy Grace's career is at rock bottom and is in the last chance saloon running enquiries into long-forgotten cold cases with little prospect of success. Then he is approached by colleague DS Glen Branson to help investigate the disappearance of a Brighton property developer, who vanished without a trace on his stag night.
