Police Inspector Peter Pascoe has stumbled upon the remains of an ancestor unjustly executed in wartime. As he delves into the mystery of his disgraced great-grandfather’s death, his partner, Detective Superintendent Andrew Dalziel, is preoccupied with a shapely animal rights activist. Eight female protesters have discovered human bones on the grounds of a drug company’s research headquarters, and the investigation has a shocking connection to Pascoe’s own family case.
