Monica Baldwin (1893–1975) was a British writer, a niece of British Prime Minister Stanley Baldwin, who was a canoness regular for 28 years. After leaving her enclosed Order, she wrote of her experiences in a series of books which received a widespread audience at the time, giving the first direct account of life in a Religious Order, from a former member, in that period.
Baldwin joined an enclosed monastery of Augustinian canonesses in 1914, a few months before the beginning of World War I. Six years later she began to think she had made a mistake but it was another 18 years before she left, convinced that she "was no more fitted to be a nun than to be an acrobat." After 28 years of consecrated life there, she made the decision to leave the life, and requested dispensation from her religious vows, which was granted by the Vatican. She left on 26 October 1941, during the Second World War 
Work and writing
Among her jobs outside were as a gardener in the Women's Land Army, as a matron in a camp for conscripted girl munitions workers, and as an army canteen hostess peeling potatoes. Once a photographer offered her a job developing "dirty pictures" in his cellar. After that she worked as an assistant librarian and then in the War Office.
In 1949, she published a memoir, I Leap Over The Wall: A Return to the World after Twenty-eight Years in a Convent. The book, later sub-titled, Contrasts and impressions after... is a memoir of some of the contrasts between life in an enclosed convent and life out in the contemporary world. Baldwin relates how she could not recall reading a newspaper during the entire course of the First World War. When she entered, the popular use of telephones, cinema and radio were in their infancy; when she left they were common in England.
Her novel, The Called and the Chosen, written as the diary of Sister Ursula Auberon, an enclosed nun at the Abbaye de la Sainte Croix, Framleghen, was published in 1957 by Farrar, Straus & Cudahy. The book followed the 1956 publication of The Nun's Story, a novel by Kathryn Hulme.
