Amy Fulford, an excellent pupil and gifted athlete at a girls' public school in Ascot vanishes one Saturday afternoon. DSI Marshe runs the local missing persons unit. He is responsible for overseeing the disappearance of Amy Fulford. But, as a late joiner and with only ten years of service, and a bullish DCS on his back, he tends to be unsure of himself. While the spiral of media interest in the missing daughter of a well-connected couple heats up, the spotlight turns on the parents who are embroiled in a bitter divorce. Amy's journal surfaces with disturbing entries about her mother's abilities - and also her father's sordid sexual activities. Marshe's DCS is convinced Marcus Fulford is responsible for his daughter's death. But Marshe himself is not so sure.
