When builders renovating a backstreet shop in King’s Lynn punch through an old wall, they uncover an articulated human skeleton—modern, not Victorian. Forensic archaeologist Dr Ruth Galloway is called in, and the discovery quickly becomes a murder investigation. But Ruth is already fighting another crisis: her university plans to close the archaeology department, threatening the life she’s built in Norfolk.
As DCI Harry Nelson’s team reopens the case, the bones are identified as Emily Pickering, a Cambridge archaeology student who vanished in 2002 after a field trip to Grime’s Graves. The inquiry spirals through old friendships and rivalries, a folklore-steeped café called the Green Child, and the unsettling return of names Ruth knows too well—especially Cathbad, whose connection to Emily is deeper than anyone expected. When Cathbad disappears and Ruth and her daughter Kate are lured underground, the case turns personal, urgent, and deadly—until the truth finally breaks the surface.
