The Black Tower

Adam Dalgliesh, newly promoted to the rank of commander, is facing a crisis in his career. Dissatisfied with his work, restless and vulnerable, he thinks of resigning from the Force. However, an invitation to visit an old family friend in Dorset appeals to Dalgliesh. But when he arrives at Toynton Grange, a private home for the disabled, he discovers that his host has died suddenly. Other more mysterious deaths follow, and Dalgliesh finds that the 'problem' is an enclosed world seething with malice, intrigue, hatred, and murder.
