Combe Island off the Cornish coast has a bloodstained history of piracy and cruelty but now, privately owned, it offers respite to over-stressed men and women in positions of high authority who require privacy and guaranteed security. But the peace of Combe is violated when one of the distinguished visitors is bizarrely murdered. Commander Adam Dalgliesh is called in to solve the mystery quickly and discreetly, but at a difficult time for him and his depleted team. Dalgliesh is uncertain about his future with Emma Lavenham, the woman he loves; Detective Inspector Kate Miskin has her own emotional problems; and the ambitious Sergeant Francis Benton-Smith is worried about working under Kate. Hardly has the team begun to unravel the complicated motives of the suspects than there is a second brutal killing, and the whole investigation is jeopardized when Dalgliesh is faced with a danger more insidious and as potentially fatal as murder. --Jacket summary.
