The five-part drama is produced by the Line of Duty, Vigil and The Pembrokeshire Murders producers, with filming overseen by executive producer and World Productions’ Head of Drama Jake Lushington.
The series introduces Doctor Joe O’Loughlin, played by Aidan Turner, who appears to have the perfect life – a devoted wife, a loving daughter, successful practice as a clinical psychologist, media profile and a publishing deal.
He’s even a hero online after rescuing a young patient who was ready to jump from the tenth floor of the hospital where Joe works.
When a young woman is found in a shallow grave in a West London cemetery, veteran police officer DI Vincent Ruiz and his young partner DS Riya Devi are assigned to the investigation. But has the young woman been murdered or is this a case of suicide?
As a successful author, Doctor Joe’s opinion is much sought after and when he meets DS Devi he’s only too willing to offer help with profiling and his expertise.
Now known for his risk-taking and rule-breaking does Joe have more to hide? His recent diagnosis with a debilitating illness could explain his behaviour. But as the investigation into Catherine’s death gathers pace, we start to ask, do we know the real Joe, or does he have a secret life?
Aidan will be joined in the cast by this year’s RTS Best Actor winner and Bafta nominee Shaun Parkes, Sian Clifford, Camilla Beeput, Adam James, Anjli Mohindra and Bobby Schofield.
Aidan Turner said: "I am thrilled to be taking on the complex and demanding role of Joseph O’Loughlin, a man with so much to give but so much to lose, and a hidden darker side."
ITV's Huw Kennair-Jones: "Peter has combined an exciting narrative full of twists and turns with the exploration of a richly compelling character in Joe O'Loughlin and has brought Michael Robotham's much loved book brilliantly to life...
"We're thrilled to have Aidan Turner to play Joe and to be working with World Productions on what promises to be a gripping new series."
The Suspect begins weekly from Monday 29th August on ITV.
