DI Steve Winwood's quiet Saturday morning is ruined when one of the guests is found murdered during a  Murder Mystery Weekend at the Fleetwood Arms Hotel. The first thing Winwood discovers is that many of the guests are members of the Rutherford Operatic And Dramatic Society (ROADS) and they all have solid alibis for the time of death. They were asleep. The deceased Martin Protheroe had switched rooms with Alan Stirling a member of ROADS. The group used this and similar events in other hotels to indulge in swinging weekends. Winwood sends DC Emma Porter undercover and she auditions for the chorus in ROADS' upcoming production of South Pacific. She goes to the Fleetwood Arms Hotel's Treasure Island themed dinner as the guest of Alan Stirling and finds herself sat on the same table where another actor suffers a fatal anaphylactic shock. Winwood continues to dig deeper into the lives and loves of ROADS and the secret life of Martin Protheroe. In a classic Agatha Christie style dénouement he gathers all the cast back at the Fleetwood Arms Hotel to uncover the culprit behind both murders.
