"The Hammer of God," readers are surprised to learn from Father Brown that the murderer is not a violent madman but rather a very respected member of the community. The Reverend Wilfred Bohun could no longer stand the scandalous behavior of his alcoholic brother Norman, who blasphemed God and humiliated the Reverend Bohun in the eyes of his parishioners. Chesterton states that Wilfred and Norman Bohun belong to an old noble family whose descendants are now mostly "drunkards and dandy degenerates." Rumor has it that there has been "a whisper of insanity" in the Bohun family.
