Murderland

One night in 1994 Carrie comes home from a party to find her mother Sally, a prostitute, had been murdered. Carrie sees a man's shadow on the wall and, whilst phoning the police, observed a man with a blood-stained hand. She is keen to help D.I. Hain in his investigation, though the crime goes unsolved.

Hain explains to Carol his own position fifteen years earlier and how he was dropped from the case because he was a client of Sally, whom he loved. Hain used Cleo's, the massage parlour where Sally worked, to gain information from her former colleagues. He suspected another policeman, Oliver, of having shady dealings with Tony Phillips, the man behind Cleo's. Hain was subsequently given early retirement. Carol decides to go under cover herself at the massage parlour to see if she can find answers.

Hain and Carol continue to dig into the past, despite death threats. Carol registers at the massage parlour as Angel and forces Whittaker, a regular client, to admit he took photographs for a pedophile ring.
