"In this intelligent novel Hammesfahr has etched with precision the thoughts of a woman on the edge of madness."—Der Spiegel

Cora Bender killed a man. But why? What could have caused this quiet, lovable young mother to stab a stranger in the throat, again and again, until she was pulled off his body? For the local police it was an open-and-shut case. Cora confessed; there was no shortage of proof or witnesses. But Police Commissioner Rudolf Grovian refused to close the file and began his own maverick investigation. So begins the slow unraveling of Cora's past, a harrowing descent into a woman's private hell.
