Suspect Season 2 is to Premiere on Channel 4

Danny turns up on Jackie's doorstep to question why the evidence of foul play he has uncovered was not mentioned in her post-mortem report. After tricking his way into her home, he discovers a link between Jackie and one of the people he has interviewed, and speculates about her role in a cover-up - only for her to turn the tables on him.

A humbled and subdued Danny returns to the mortuary to say a final goodbye to Christina in the company of ex-wife Susannah. However, any attempts to reminisce about Christina as a little girl quickly turn into recriminations about why neither of them was aware of the life she was leading.

The circumstantial evidence that Danny has collected in the course of his encounters now leads him to what he expects will be a showdown with Christina's murderer - urbane pharmaceutical industry executive-turned-entrepreneur and investor Harry Carr. But when he goes to challenge him, Danny is taken by surprise.

Danny goes to confront his former police partner Ryan. Initially, he does not mention the CCTV footage that proves Ryan was with Christina shortly before she died. But as his old friend becomes pricklier and more evasive in response to his questioning, it becomes too much for Danny and he reveals what he knows - prompting an extremely violent reaction.

Against Maia's advice, Danny goes alone to meet with Christina's supplier, who is revealed to be Jaisal Batra, a corrupt former police officer-turned-club owner. Initially, Jaisal easily parries his ex-colleague's clumsy attempts at interrogation, but Danny's behaviour is increasingly volatile, and he takes drastic action in exchange for information from Jaisal.

Bruised by his encounter with Nicola, Danny goes to The Crimson Orchid gentlemen's club to look for Maia, who Nicola has accused of corrupting Christina. Maia stonewalls Danny's questions, but when he tells her that Christina may have been murdered, her façade of indifference cracks. Danny knows that Christina was involved in criminal activity, and he assumes Maia has lured her into prostitution, but in the face of her angry denials, he realises that Christina was selling drugs.

Detective Danny Frater arrives at the apartment where his estranged daughter Christina's body was found, and manages to find his way inside. As he carries out a search, he is startled to discover a young woman hiding in the bedroom. Although she does her best to escape, Danny manages to prevent her and forces her to answer his questions. She turns out to be Christina's wife, Nicola, and their subsequent conversation reveals as much about Danny's estrangement from his daughter as it does Christina's increasingly dark and complicated life.

When veteran detective Danny Frater turns up at a hospital mortuary for what he thinks is a routine ID check, he gets a devastating shock. The deceased - a young woman - turns out to be his estranged daughter, Christina. According to the post-mortem report, she's taken her own life. Although the pathologist, Jackie Sowden, insists that the evidence points overwhelmingly toward suicide, Danny refuses to accept her findings, and he forces Jackie to take him through her examination step-by-step.
