The Innocence and Wisdom of Father Brown (Barnes & Noble Library of Essential Reading) by G. K. Chesterton
Contrary to first impressions, G. K. Chesterton's "Father Brown" is not senile, nor easily rattled. In fact, this village priest wanders into challenges that pale in comparison to the things he has heard through the screen of the confessional. For to hear Father Brown tell it, crime is a manifestation of sin: the criminal must be caught, but he or she must also be saved; the culprit has to be locked up, but the spirit must be freed.
