The ghost fields: a Ruth Galloway mystery

"The macabre discovery of a downed WWII plane with the pilot's skeleton still inside leads Ruth and DCI Nelson to uncover a wealthy family's secrets in the seventh Ruth Galloway mystery" --
"Norfolk is suffering from record summer heat when a construction crew unearths a macabre discovery--a downed World War II plane with the pilot still inside. Forensic archaeologist Ruth Galloway quickly realizes that the skeleton couldn't possibly be the pilot, and DNA tests identify the man as Fred Blackstock, a local aristocrat who had been reported dead at sea. When the remaining members of the Blackstock family learn about the discovery, they seem strangely frightened by the news. Events are further complicated by a TV company that wants to make a film about Norfolk's deserted air force bases, the so-called Ghost Fields, which have been partially converted into a pig farm run by one of the younger Blackstocks. As production begins, Ruth notices a mysterious man lurking on the outskirts of Fred Blackstock's memorial service. Then human bones are found on the family's pig farm. Can the team outrace a looming flood to find a killer?"--
