The Lighthouse: P. James

Combe Island off the Cornish coast is a restful retreat for the rich and the powerful. But the peace of the island is violated when one of its distinguished visitors is murdered.

Adam Dalgliesh is called in to solve the mystery quickly and discreetly, but at a difficult time for him and his depleted team. Hardly have the team begun to unravel the complicated motives of the suspects that there is a second brutal killing and the whole investigation is jeopardised when Dalgliesh is faced with a danger more insidious and as potentially fatal as murder.
