A book by G. K. Chesterton detailing a popular theme both in his own philosophy, and in Christianity, of the "holy fool", such as in Dostoevsky"s The Idiot and Cervantes" Don Quixote. This is a book in two parts. The first, “The Enigma of Innocent Smith,” concerns the arrival of a new tenant at Beacon House, a London boarding establishment. Like Mary Poppins, this man (who is tentatively identified by lodger Arthur Inglewood as an ex-schoolmate named Innocent Smith) is accompanied by a great wind, and he breathes new life into the household with his games and antics. During his first day in residence the eccentric Smith creates the High Court of Beacon; arranges to elope with Mary Gray, paid companion to heiress Rosamund Hunt; inspires Inglewood to declare his love for Diana Duke, the landlady’s daughter; and prompts a reconciliation between jaded journalist Michael Moon and Rosamund.
