A girl is found dead on a beach with a false identity - the identity of another girl who has been missing for years. A courting couple are murdered and 'posed' as Hansel and Gretel in the woods outside Hamburg. A beautiful Hamburg model is strangled and posed as if asleep in Sternschanzen Park. A massive controversy erupts when an author publishes a novel, the premise of which is that one of the brothers Grimm was a serial murderer of children. Hauptkommissar Jan Fabel and his team are drawn into the dark and menacing world of traditional German folk tales and their meaning - and onto the trail of a terrifying serial killer.
