"Maybe Sister Margaret Mary is a saint." "Nonsense The poor young woman has been out of her mind for years." "That's a lie " "It is not " "It is " The gossip in town raged on. The nuns themselves did not know what to think about the Sister who reportedly saw Our Lord. Even the superior Mother Greyfie didn't know what to think. But one day, she decided to settle the question once and for all. For some time now Sister Margaret Mary had been seriously ill. Well, if Our Lord would cure her immediately, and keep her in perfect health for five months, she, Mother Greyfie, would have no more doubts about the so-called apparitions, but would work to spread devotion to the Sacred Heart. So off went Mother Greyfie to the infirmary, where Sister Margaret Mary lay sick in bed. What was going to happen now? This book gives the answer. It also tells about Margaret's painful days at home, her difficulties in becoming a nun, about St. Claude de la Colombiere, about the lonely young Catholic duchess, and about Our Lord's message concerning His Sacred Heart. In short, this is the remarkable story of St. Margaret Mary Alacoque and the wonderful promises of the Sacred Heart of Jesus."
