England, early 20th century. The Beacon guesthouse in London welcomes an unexpected and eccentric visitor, who arrives tumultuously, accompanied by a strong wind like another Mary Poppins, and disrupts the tenants with his strange tricks. Innocent Smith is a formidable-looking man who brings a new breeze to the dull Beacon and entertains the tenants in a bizarre way. However, just as the guesthouse is brimming with happiness, two academics appear bearing terrible news: Smith is wanted by the authorities for robbery, abandonment of his wife, polygamy, and attempted murder. In the second part of the book, a dramatic trial follows, where Chesterton's writing brilliance captivates even the most demanding reader. A blend of Christ-like foolishness and quixotism mixed with the author's comically existential disposition.
