Part Three - Compulsion: Rawton addresses the team, and puts forward the theory that rape victim Terri's death was not suicide, but murder. Whilst Cork and Singh voice doubts, Spears supports Rawton's theory. Spears returns to the riverside where Terri's body was found, and makes a major break-through when a passer-by reveals that his wife saw Terri's body being dumped. Later, Spears decides to keep an eye on Cork, and follows him to a pub where he meets up with an old mate. On her return, Spears spots a man lurking outside her flat, but he turns out to be her old friend Eddie, who works for the Thames Valley police. After trying to dig up information on Cork, Eddie disappears without trace. (thetvdb.com)
