The Monk is the most sensational of Gothic novels. The main plot concerns Ambrosio, an abbot of irreproachable holiness, who is seduced by a woman (or perhaps a demon) disguised as a novice, and who goes on to sell his soul to the Devil. An extravagant blend of sex, death, politics, Satanism, and poetry, the work greatly appealed to the Marquis de Sade.

The Broadview edition includes a critical introduction and appendices of historical materials that address the novel's literary sources (in English, German, and Greek literature), historical contexts (the French Revolution, slavery and abolition debates, sexuality), critical reception, and influence.
