THE BOOK: An epic arch sinfulness, The Holy Sinner is one of Thomas Mann's great works. From the incestuous union of the two beautiful children of the Duke Grimald of Flanders a boy is born. Left to die at sea, the child is eventually rescued & brought up in holiness on the channel islands. Only after marrying his mother does the child come to realise the unwitting - and witting - extent of his crime against nature.
