The body of a popular local swimming coach is pulled from a pool and the Kingsway detectives are called upon to investigate the murder. The coach, Jimmy O'Sullivan, was a life-long friend of Ted Hudson and rumours of his possibly being a paedophile do not sit well with the Senior Sergeant. Theo offers his support to Sophie, who is feeling hard-done-by, however an intimate moment between the two is interrupted by her four-year-old son. Back at work, Theo is forced to reveal Sophie's secret to Hudson who, as she feared, quickly reassigns her to a sexual assault case before finally suggesting she stick to desk duty for the time being.
