When a digger at a construction site uncovers a World War II airplane with a body inside, the police consult with forensic archaeologist Ruth Galloway to find out if the plane has been there since the war. Based on soil samples, Ruth concludes that the plane has been there all along, but that the body inside, while long dead, was moved there recently. DNA tests show that the pilot was Frederick Blackstock, from a local wealthy family. He moved to the states before the war and fought for the Americans. How, then did he end up in a plane near his birthplace, while all this time his family thought he died in the war? In this seventh entry in the Ruth Galloway series, Griffiths writes a satisfying mystery that forwards the personal lives of the recurring characters and gives the reader an interesting puzzle to solve, partly owing to the rich heritage of the Norfolk coast. It will be published in May.
