Set in 1940 amid the cramped squalor of Warsaw's Jewish ghetto, American author Zimler's eighth novel is the story of moral breakdown induced by the desperate struggle to survive. Elderly psychiatrist Erik Cohen shares a tiny apartment with his niece and her nine-year-old son Adam, who goes missing. His body is discovered, one leg amputated, entangled in the barbed wire surrounding the ghetto. When a girl's body turns up in similar circumstances and minus a hand, Cohen begins to think the unthinkable – that a Jewish traitor may be luring children to their deaths – and starts to investigate. Beautifully written, moving and disturbing, this packs a powerful, emotional punch.
