Watch The Bill online: Episode 65 Episode 057

The fourth victim of the serial killer is found on the banks of the Thames, just as Peter Baxter predicted. Despite Baxter's confession and inside knowledge of the case, Acting DI Nixon begins to have serious doubts about his guilt. Tormented with guilt of his own, Des Taviner discharges himself from hospital and pens a lengthy confession of his role in the Sun Hill fire. He tracks down Reg Hollis who is investigating an assault on a schoolboy. The pair track down the attacker, a young man who threatens to jump off a building. Taviner saves him, but is on the verge of killing himself when Hollis convinces him he's suffered enough. Talking to Baxter's prison warden, Nixon confirms that he is not the killer, and DCI Ross is furious when she interrupts his press conference with the news.
