Darcy is off on another one of his top secret jaunts, and Grandad is busy helping wayward youths avoid lives of crime. So when Georgie's friend Belinda inherits an old cottage in Cornwall she jump at the chance. The creaky old cottage is called White Sails-- and is completely uninhabitable. Rose Summers, a woman Belinda knew as a child when she spent time in Cornwall, invites them to stay at Trewoma Hall, owned by her husband, Tony. Belinda confesses that she never liked Rose and had a fling with Tony years ago, so staying with them is far from ideal. When a member of the household is found murdered and all clues point to Belinda as the prime, Georgie will have to sift through the ruins of the past. -- adapted from jacket.
