A series of unexplained and bizarre suicides forces Beverley into close contact with her former lover, the renegade forensic pathologist John Eisenmenger, who is already investigating the sudden suicide of his colleague Daisy Pemberton. Eisenmenger conducts autopsies on the victims and discovers all their deaths are linked by their earrings. When he convinces Beverley to pursue the trail of the earrings they become enmeshed in a frightening web of mental manipulation that brings them to the edge of being the instruments of their own violent deaths.
