This is the book which took the reading public by storm when it was first published in 1796-and modern readers find it just as exciting today. One critic has called it 'A mass of murder, outrage, diablerie and indecency'. The monk, Ambrosio, of saintly reputation, is seduced by a young woman, Matilda, who has entered his monastery disguised as a boy and captured his interest. Once his vows are broken Ambrosio's fall is rapid. With the help of Matilda, who is in league with the Devil, he courts one of his penitents, but has to commit murder before his desires are satisfied. Then, in a panic, he kills his mistress to escape detection. But it is too late. The inquisition captures and tortures him. One last pact with the Devil seems to hold out hopes for his escape, but even Satan has deceived him.
