Episode list

With each of the suspects having a motive, opportunity or connection to David Walker, Cassie and Sunny try to join the dots to discover who actually killed him 25 years earlier.

Despite a shocking event, the Bishop Street team start to piece together which of the four was responsible for the murder of Matthew Walsh but it is pathologist Leanne Balcombe who provides the crucial piece of evidence.

One suspect is now dead and another in custody but evidence found at his flat is dismissed by Mrs Reid as not belonging to Hayley. However it does connect to another unsolved murder and a shocking admission follows, finally closing the case. Meanwhile the remaining two men find positive support through two women in their lives, ending their torment.

Cassie turns her attention to investigating the goings-on at the Brentford house and the theory that one or more of the suspects may have been abused at the gatherings that took place there.

Following the murderous attack on Pete, Sandra Rayworth is charged with incitement. Cassie finds evidence to incriminate Elliot, though only fifteen at the time of Hayley's death, but James quizzes him and brings him to the police, who dismiss him from their enquiries. Chris makes a startling confession whilst Tim's daughter Emma learns the truth about her father's violence from Derran just before an arrest is made for Hayley's murder.

Mel Hollis's account convinces Cassie that all four men were lying, particularly Pete, whose criminal past makes him the prime suspect and ends his marriage. However Tim's first wife Derran - who stayed at the cottage let with him - paints a less than flattering picture of him whilst Chris's estranged daughter Maya also reveals her father's dark secret. Cassie loses the file on Pete as he prepares to leave the country, having passed on a message about Elliot but Sandra Rayworth's toxic web-site marks him out as a victim.

Cassie and Sunny interview two of the suspects again and get closer to the truth of what happened to Walsh. Balcombe believes she may have found the cause of death.

Jason finds it difficult to process his father's death and asks Cassie to see his dad's body following his outburst at stepsister Becca.
