From The Glories of Mary by St. Alphonsus Liguori, a continuation of the chapter named Various Examples Appertaining to the Most Blessed Virgin Mary:
47. There lived in Germany a young girl, called Agnes, who had been guilty of incest in the first degree. She fled into a desert, and there gave birth to a child. The devil, in the form of a religious, appeared to her, and persuaded her to throw the child into a pond. But after wards, when he proposed to her to throw herself in also, she said: "Mary, help me," and the devil disappeared.
48. A soldier once made a compact with the devil, that he would sell his wife to him for a certain sum of money. He was taking her to a wood to fulfil his promise, when he passed before a church dedicated to the Virgin. His wife begged him to allow her to pay her devotion to Mary in that church; but as she entered it, Mary came forth from it, and taking the form of the woman, accompanied the husband. When they reached the wood, the demon said to the man: "Traitor, why have you brought me, in stead of your wife, my enemy, the mother of God?" "And thou," said Mary, "how hast thou dared to think of injuring my servant? Go, flee to hell." And then turning to the man, she said: "Amend your life, and I will aid you." She disappeared, and that wretched man repented, and amended his life.
49. A very sinful woman who lived in Meseico, having fallen ill, repented of her life, and made a vow to Mary, that if she would restore her to health she would present her with her hair. She was cured, and she cut off her hair, making an offering of it to the statue of the Virgin. But the woman again fell into sin, again fell ill, and died impenitent. Then Mary one day afterwards spoke from that statue to Father Giaramaria Salvaterra, and said: Take those locks from my head, for they belong to a lost and sinful soul, and are not befitting the head of the mother of purity. The Father obeyed her, and threw them himself instantly into the flames.
50. A Saracen, named Petran, made captive several Christians in Spain, who recommended themselves to the holy Virgin. Mary appeared to the Saracen, and said to him: "Petran, how dare you to hold my servants slaves? Release them immediately obey." And the Moor answered: "Who are you whom I am to obey?" I am," said she, "the mother of God; and because they have had recourse to me, I wish you to give them their liberty." Then the heart of Petran was changed, he set the Christians free, and presented himself to the Virgin. She first instructed him, and then she herself baptized him in a fountain, near which a church was built, and a Benedictine monastery.
51. A certain canon, while he was repeating some devotions in honor of the divine mother, fell into the river Seine and was drowned, and being in mortal sin, the devils came to take him to hell. But Mary appeared at the same time, and said to them: "How have you dared to take possession of one who died praising me?" Then turning to the sinner, she said: "Repent," and be particularly devout to my Conception. He was restored to life, became a religious, and never ceased to thank his deliverer, and every where to propagate the devotion to her Immaculate Conception.
52. Whilst the monks of Clairvaux were reaping in the fields, and praising the queen of heaven, most holy Mary was seen caressing them, and two other saints wiping their sweat.
