This is the fourth collection of mysteries featuring the very smart and even more devout catholic priest, Father Brown. (It follows The Innocence of Father Brown , The Wisdom of Father Brown and The Incredulity of Father Brown .) Father Brown is probably the most unconventional detective of fiction: short and dumpy, extremely shy, unvaryingly kind, and utterly unselfconscious. His secret? As a priest he has developed a far-reaching understanding of how we all feel and think. Being profoundly humble, he is able to imagine how he, personally, could be led to commit a given theft, murder or other crime. With this in mind, he is generally able to figure out who did commit it. - Summary by Kirsten Wever
