G.K. Chesterton's Father Brown stories are widely considered to be some of the finest detective short stories ever published, offering vivid writing, brilliant puzzles, biting social criticism, and metaphysical explorations of life's great questions. This book presents the first in-depth analysis of his works both as classics of the detective genre and as meaningful philosophical inquiries. The Father Brown stories are examined along with Chesterton's less well known fiction, including the short stories about Mr. Pond, Gabriel Gale, Basil and Rupert Grant, Horne Fisher, Dr. Adrian Hyde and Philip Swayne, and the novels The Man Who Was Thursday and Manalive.
