When builders find a human skeleton behind a wall, they call for DCI Harry Nelson and Dr Ruth Galloway, Head of Archaeology at the nearby University of North Norfolk. The bones are identified as the remains of Emily Pickering, a young archaeology student who went missing in the 1990s. Suspicion falls on her Cambridge tutor and also on another course member - Ruth's friend Cathbad, who is still frail following his near death from Covid. The unmissable new book in the Dr Ruth Galloway Mysteries.
