Father Gabriel has finally returned to St Mary's Abbey, but all is not well in the sleepy Wiltshire village of Sutton Westford. Joseph Beaumont, a former village boy turned London property developer, has returned to build a row of houses on the grounds of a disused mine. A local opposition group - led by Joseph's boyhood nemesis - campaigns to stop the development, and Joseph finds himself the target of increasingly menacing threats. Then, workmen make a gruesome discovery on the building site: the skeleton of a child who went missing thirty years before, while the Great War was raging. Fr Gabriel is called in to investigate, but the task seems impossible. How can he uncover a secret that has been carefully hidden for three decades? Is the killer even still alive? Worse, as the tragic details emerge of a lost little girl's final moments, Gabriel is tormented by the memory of his own daughter and the life that was stolen from her many years before.

Missing Presumed Lost explores the themes of childhood innocence, guilt, and the responsibilities faced by society to protect the young. The book also delves deeper into Gabriel's own troubled past and the need to lay it to rest.
