Bodies are being exhumed at King's Lynn's cemetery, the bones moved to higher ground to avoid flooding. But when the coffin of murdered pub landlady Nora Tilden is hauled up into the light there's a grim discovery: the twisted corpse of a young black man, killed by a billhook blow to the head, and dumped in the grave on the night Nora was buried twenty-eight years earlier. The police are baffled by a bewildering and brutal murder. Who was this young man? Was he the victim of a racist crime? When DI Peter Shaw, DS George Valentine and their team are put on the case their investigation first leads them to The Flask, Nora's pub just along the riverbank, where her family hides more than one dark secret and it's soon clear no one can be trusted. Will Shaw and Valentine be able to get to the shocking truth behind the murder before it's too late and the ghosts from the past claim another victim?
