The Suspect: Release date, cast and news for Aidan Turner ITV thriller

As the detectives begin to dig more into Joe's past, they start to suspect that he may be holding onto a dark secret – but was he involved in the death at hand?

With a stellar cast featuring the likes of Shaun Parkes and Anjli Mohindra, The Suspect brings Michael Robotham's novel of the same name to life – and if you can't get enough of the story, there's more to the Joe O'Loughlin tale in Robotham's book franchise.

Turner spoke about his own research for the series, meeting a Parkinson's patient to inform his own character who is dealing with a Parkinson's diagnosis in the series, while the show's boss told RadioTimes.com that it almost got made five years ago, but due to a rights issue is just coming to screens now.

What is The Suspect about?

The Suspect is based Michael Robotham's novel of the same name and focuses on Joe O'Loughlin, played by Aidan Turner.

The official synopsis for the series says that O'Loughlin "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."

It continues: "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 degenerative condition 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? And has his work as a clinical psychologist allowed him to develop a criminal mindset? Or worse?"
