Paranoid tells the story of a female GP murdered in a rural children’s playground surrounded by eyewitnesses and the hunt to find the killer.
Game of Thrones star Indira Varma and Spooks’ Robert Glenister are among the cast for the eight-part series coming later this year.
The show will be set in the fictional Cheshire town of Marshwell, but viewers will certainly be able to do some location spotting when the programme hits screens.
ITV were coy on specific settings, but crews have been spotted on Helsby Hill and in Tarporley.
Paranoid will see detectives from ‘Cheshire Police Force’ take on the murder investigation which takes them unexpectedly across Europe as they delve deeper into the mystery.
Producer Tom Sherry added: “Paranoid lays bare the human and emotional story of a group of detectives hell-bent on capturing a killer, but there are unexpected twists and turns every step of the way.”
Also among the cast are Neil Stuke, Lesley Sharp and Kevin Doyle.
The first filming for the show began in Northwich in March. While scenes will also be shot in the German cities of Cologne and Dusseldorf.
Paranoid has been penned by acclaimed writer and producer Bill Gallagher whose previous credits include The Paradise and Lark Rise to Candleford.
Manchester-based Red Production Company have also been responsible for Happy Valley, Cucumber and Scott and Bailey.
ITV director of drama Steve November said: “Paranoid is a taut, compelling eight-part series with all the hallmarks of a classic psychological thriller.
“Bill has written some incredibly well-defined characters who embark on a terrifying murder investigation as it becomes evident from the outset that malevolent forces are at play.”
Paranoid will be broadcast on ITV later this autumn.
