The real name of Edmund Crispin was Bruce Montgomery. He was born in 1921 in Chesham Bois, Buckinghamshire, and attended St. John's College in Oxford, where he graduated in Modern Languages and was an organist and choirmaster for two years. When asked about his hobbies, Crispin used to say that what he liked the most in the world was swimming, smoking, reading Shakespeare, listening to operas by Wagner and Strauss, wandering around and looking at cats. On the contrary, I felt great antipathy for dogs, French films, modern English films, psychoanalysis, psychological and realistic detective novels, and contemporary theater. He published nine novels, as well as two collections of stories, all featuring the Oxford professor and amateur detective Gervase Fen, an eccentric teacher based at the fictional St. Christopher's College. Works that earned him a place of honor among the most important English authors of classical detective novels. Impedimenta undertook with his masterpiece, La juguetería errante (1946; Impedimenta, 2011), the publication of the Gervase Fen saga, which has continued with The Song of the Swan (1947; Impedimenta, 2012), Bloody Love Works (1948; Impedimenta, 2014), The mystery of the golden fly (1944, Impedimenta, 2015) and Murder in the cathedral, and buried for pleasure> (1949; Impedimenta, 2017). Crispin stopped writing in the fifties, but continued to write reviews of detective novels and science fiction for the Sunday Times. He died of a heart attack in 1978.
