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's, whom he loved. Hain used Cleo's, the massage parlour where Sally worked, to gain information from her ex-colleagues. He suspects Inspector Oliver of shady dealings with Tony Phillips, the man behind Cleo's. Hain was subsequently given early retirement. Carol herself goes undercover at Cleo's, seeking answers.
