This rumpled, clumsy detective-priest appeared in 52 short stories, 48 of them collected in five volumes during Chesterton's lifetime. The strongest of the stories are the earliest--"The Blue Cross," "The Secret Garden," "The Wrong Shape," "The Sins of Prince Saradine," "The Honour of Israel Gow," and seven others that all appeared in the first collection, The Innocence of Father Brown (1911), a work the prominent pseudonymous American mystery writer Ellery Queen called "the miracle-book of 1911" and "one of the finest volumes of short stories ever conceived and written." These tales were written when inspiration was strong upon Chesterton, and the key concept of Father Brown and his potential were fresh and exciting to the author.

Each of these early stories is a tightly plotted gem, with fresh dialogue, surprising twists, gorgeous scene-painting, and--most important--a main character who solves and thwarts crimes not by CSI-style clue-chasing or Sherlockian inductive reasoning but by his knowledge of the passions that motivate men. The key to Father Brown's powers of insight lies in the fact that among his daily duties is hearing the confessions of his flock. "Has it never struck you that a man who does next to nothing but hear men's real sins is not likely to be wholly unaware of human evil?" he asks one astonished would-be robber--his greatest antagonist (and in time his best friend), Hercule Flambeau.
