Based on a popular folk legend. Yoshe Kalb is a brilliant and haunting novel set in nineteenth-century Galicia. Nahum, a naive and sensitive young man, is thrust into the decadent world of corrupt and competing hasidic dynasties when he marries the daughter of a powerful Rabbi. I. J. Singer explores the darker side of hasidic life and the forces of sin and saintliness that vie for Nahum's soul.
