# The Vanishing of Vaudrey explained — The Secret of Father Brown > Chapter companion for The Secret of Father Brown by G. K. Chesterton. ## What happens Father Brown and Evan Smith investigate the murder of Sir Arthur Vaudrey, uncovering that John Dalmon killed him in the barber's shop while the barber briefly stepped outside. The priest reveals that the real motive was a horrible vengeance, not blackmail, and that Vaudrey was the blackmailer, not Dalmon. The barber, fearing false accusation, disposed of the body but forgot the victim's hat, leading to the discovery. ## Themes in this chapter ### The Nature of Evil and Sin Father Brown reflects on the 'horrible tale of hatred' and the abyss of human vengeance, highlighting the depth of evil in Vaudrey's planned revenge. ### The Psychology of the Criminal Explores the motives of Dalmon (vengeance) and the barber (fear), contrasting their psychological states. ### Appearance vs. Reality The initial assumption that Dalmon was a blackmailer is overturned; Vaudrey, the apparent victim, is revealed as the true blackmailer and schemer. ## Character check-ins ### Father Brown Investigates the murder, deduces the barber's innocence and Dalmon's guilt, and reflects on the depths of human vengeance. ### Evan Smith The secretary who accompanies Father Brown, initially suspects Dalmon of blackmail but is shocked to learn he is the murderer. ### John Dalmon Revealed as the murderer who cut Sir Arthur Vaudrey's throat in the barber's shop, driven by a motive of vengeance. ### Sir Arthur Vaudrey The victim, a rich man who was blackmailing Dalmon and planning a hideous vengeance, killed while being shaved. ### Sybil Rye A pale, sensitive young woman who was Vaudrey's ward and Dalmon's love interest; her character and history are central to the motive. ### Mr. Wicks The barber who discovered the murder in his shop and disposed of the body out of fear, but is exonerated by Father Brown. ## Key lines > Merciful God, what a horrible revenge! ... What a horrible tale of hatred! What a vengeance for one mortal worm to take on another! Father Brown exclaims in horror at the depth of vengeance Vaudrey planned, calling it a tale of hatred beyond comprehension. _Reflects the theme of evil and the priest's moral shock._ > You assume that the poor man was blackmailing the rich man. As a matter of fact, the rich man was blackmailing the poor man. Father Brown corrects the assumption that Dalmon was blackmailing Vaudrey, revealing that Vaudrey was the blackmailer. _Key reversal of appearance vs. reality._ > I was thinking of a much more horrible tale than that; though, of course, that was horrible enough, in its way. But that was much more comprehensible; almost anybody might have done it. In fact, it was very nearly an act of self-defence. Father Brown distinguishes Dalmon's murder as almost self-defense compared to Vaudrey's far more terrible crime. _Highlights the relative morality and the psychology of the criminal._ ## Links - HTML: https://www.betterreads.online/discover/the_secret_of_father_brown_se/chapters/the-vanishing-of-vaudrey - Book: https://www.betterreads.online/discover/the_secret_of_father_brown_se - All chapters: https://www.betterreads.online/discover/the_secret_of_father_brown_se/chapters
