Nixon and Wallis concentrate on the Royal Navy link to the serial rapist, and interview a Scottish prostitute whose rape over ten years previously matches the profile - and may have started the rapist off. Dunbar hides a press clipping of an article she wrote about the incident, but fears for her cover when a journalist colleague arrives at the station to interview Powell as the 'new face of Sun Hill'. Powell investigates what looks like another homophobic hate crime when a man is attacked outside a gay club. Murphy is shocked when she recognises her son Conor on the CCTV, and Powell is forced to arrest Conor for GBH. Carver and Harman investigate when a fortuneteller has her crystal ball stolen.
