Friends of a Lifetime: Nun, the Infidel and the Superman by Felicitas Corrigan
At first sight there was little if anything to link George Bernard Shaw and Sydney Cockerell with the enclosed Benedictine nun, Dame Laurentia McLachlan. She made it clear from her first meeting with each man that it was friendship she had to offer, rather than adulation. The author, a nun of Stanbrook Abbey, has woven their letters into this book, showing the firm if stormy relationship between the three.
