The Shape of Sand by Marjorie Eccles
Charnley was once the proud Edwardian home of the Jardine family renowned for entertaining the local gentry with lavish parties. Yet four decades later when the house is sold and the family split up, dark, painful secrets long since buried begin to surface for Harriet Jardine. The facade of a once respectable family begins to slide when local workmen stumble on a series of hidden letters that lead to the discovery of a body brutally murdered.
