Unnatural Causes, Paperback - P. D. James

Superintendent Adam Dalgliesh has been looking forward to a quiet holiday at his aunt's cottage on Monksmere Head, one of the furthest-flung spots on the remote Suffolk coast. The mutilated body of a local crime writer, Maurice Seaton, floats ashore in a dinghy, dragging Adam Dalgliesh into a new and macabre investigation.
