The Suspect

Series overview

Doctor Joe O’Loughlin, played by Aidan Turner, 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 (Shaun Parkes) and his young partner DS Riya Devi (Anjli Mohindra) 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 the woman’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?

Episode 4

Joe (Aidan Turner) is knocked sideways when an old grudge rears its head. With the net closing in, he flees to his Dad’s house for sanctuary. Trying to plan his next move, Joe is blindsided by an unlooked-for discovery. Then Julianne (Camilla Beeput) comes under threat, and Joe is forced to move on.

For DI Ruiz (Shaun Parkes) and DS Devi (Anjli Mohindra), the case now looks crystal clear and they step up their efforts to arrest those responsible. But Ruiz has a nagging doubt that he is missing something – he just can’t put his finger on it.

Joe has one last chance to uncover the truth. With the help of those still loyal to him, he must dig deep into his own past to understand what is happening in the present.
