The Nun's Story is a 1956 novel by Kathryn Hulme. The book was a Book of the Month selection and reached #1 on the New York Times best-seller list.
Hulme wrote the book based partly upon the experiences of her friend, Marie Louise Habets of the Sisters of Charity of Jesus and Mary, a Belgian nurse and an ex-nun whom she met while working with refugees in post-war Europe. The author sponsored the former nun's immigration to the United States, and later converted to Catholicism. It is often erroneously stated that the book was based upon Hulme's own experiences.
The lead character of the book, Sister Luke (pre-convent name Gabrielle Van Der Mal), finds her faith tested in Africa where she finds herself at odds with headstrong Dr. Fortunati, operator of a remote Congo hospital, with whom she gradually builds respect, and again during World War II, when she is ordered not to take sides. Ultimately, Sister Luke is forced to decide whether to remain in the convent or return to the outside world.
Gabrielle/Sister Luke is stretched between her desire to be faithful to the rule of her congregation and her desire to be a nurse. As a nun she must remove all vestiges of "Gabrielle Van Der Mal" and sublimate herself into the devoted bride of Christ. As a nun there is no room for her personal desires and aspirations. Ultimately, the conflict between her devotion to the Church and the nursing profession, juxtaposed with her passionate Belgian patriotism and her love of her father (killed by Nazi fighter planes while treating wounded) bring her to an impasse, which serves as the dénouement of the novel.
In 1959, The Nun's Story was adapted by screenwriter Robert Anderson and director Fred Zinnemann. The Nun's Story starred Audrey Hepburn as Sister Luke. It was a critical and box office success, and Hepburn was nominated for an Academy Award for the third time.
Hepburn met Marie-Louise Habets while preparing for the role, and Habets later helped nurse Hepburn back to health following her near-fatal horse-riding accident on the set of the 1960 film The Unforgiven.
