Father Brown is a fictional Roman Catholic priest and amateur detective who is featured in 53 short stories published between 1910 and 1936 written by English novelist G. K. Chesterton. Father Brown solves mysteries and crimes using his intuition and keen understanding of human nature. Chesterton loosely based the character on the Rt Rev. Msgr. John O'Connor (1870–1952), a parish priest in Bradford, who was involved in Chesterton's conversion to Catholicism in 1922. Includes a biographical introduction by Karl Wurf.
