Ambrosio, the abbot, is the perfect monk, head of an abbey in Madrid, and the idol of the city, a young, handsome, charismatic man, with a spellbinding voice, that thrills the congregation at his church. All the people flock to it, to hear his sermons, five minutes after the bells ring, the church is overflowing, and the noble families are there, silently the assembly listens, a living saint, they witness, the proud people are ecstatic, in this modern age (the 1700's), God has sent them Ambrosio! The Capuchin Friar (an order of independent Franciscans), the Monk, is not what he appears to be, everything, a mirage, the orphan, found at the door of the abbey, as an infant, raised in the monastery, never leaving its grounds, nobody knows where the child came from... Now evil thoughts permeates his curious mind, lust and debauchery, after thirty dull years, the Monk, wants to have some fun, the deadly boredom must end soon, risk his reputation, if only the abbot had a chance...Ambrosio is close to a novice by the name of Rosario, his only friend, who mysteriously arrived at the abbey, this young gentleman, always covers his face, keeps to himself, except for the abbot, their discussions are what the monk looks forward to, during the bleak daily ennui. But finally in the garden of the abbey, Rosario reveals to Ambrosio, he's a she, a woman called Matilda, of course , after a short hesitation, carnal knowledge commences, that "She" looks like the Madonna, doesn't hurt. The abbot soon shows lack of interest, a new, fresh conquest is needed, the very accommodating Rosario/Matilda , through witchcraft, helps him, try to violate another innocent woman... Midnight, at the cemetery, he hears the owls ominous shrieks, opens the gate, into the vast, dark, eerie underground vaults of the abbey's graveyard, jointly used by the nearby convent. Ambrosio slowly descends the forbidding stairs, his heart is pounding, a flickering lamp to show the many decaying bodies, unknown vermin creeping around the horrific scene, while the monks and nuns above, hold a sacred procession, viewed by the citizens of Madrid, he goes on, until he reaches the tomb of the supposedly dead, Antonia , the drugged girl, is still alive and waking up just now, she see him and thinks all will be safe, the Monk moves closer.......Later he hears the sound of footsteps approaching him, fiend, friend or enemy? The uneasy monk awaits in the gloom, is his destiny, death or life? ...Condemned when first published, in England, in 1796, and thus a bestseller, considered now, the Gothic classic novel, even though the twenty -year- old British author, uses Italian names in Spain, murder, incest, parricide, lascivious men and willing women (including an old maid).
