The affluent seaside resort of Smalting is unaccustomed to crime. So when human remains are found beneath the floorboards of a beach hut, the community is awash with suspicion. Amateur sleuths Carole Seddon and best friend Jude are drawn into the mystery, and their suspicion quickly falls on attractive Philly Rose, a young Londoner newly arrived in the area, whose boyfriend has recently vanished. Meanwhile, Kelvin Southwest, caretaker of Smalting’s beach huts, seems to be hiding a dark secret, while Reginald Flowers, pompous President of the Smalting Beach Hut Association, becomes increasingly defensive about his own history. When the bones under the beach hut are identified, the ghosts of the past are painfully reawakened, and long-hidden secrets begin to surface.
