The novel is a postmodernist narrative that follows the adventures of the reader, who is trying to read a book called "If on a Winter's Night a Traveller." However, the reader keeps encountering obstacles that prevent him from finishing the book, including printer's errors, censorship, and interruptions from other characters. The story is interspersed with the beginnings of ten different novels, each interrupted at a moment of suspense. The book is a meditation on reading, writing, and the nature of narrative itself.

"The Baron in the Trees" tells the story of a young Italian nobleman who, in a fit of rebellion, climbs a tree and vows never to touch the ground again. He spends the rest of his life living in the treetops, observing the world from above, and engaging in adventures with bandits, revolutionaries, and lovers. Despite his self-imposed exile, he becomes a symbol of freedom and individuality, ultimately influencing the course of European history.

This novel is a complex and richly detailed exploration of a crime in 1920s Rome, where an investigation into a theft and a brutal murder in an apartment building on Via Merulana becomes a sprawling narrative that delves into the social, political, and cultural fabric of Italy. The detective in charge of the case navigates through a maze of clues, red herrings, and eccentric characters, revealing not just the underbelly of Roman society but also the inherent chaos and absurdity of life. The narrative is characterized by its linguistic inventiveness, with a mix of literary Italian, Roman dialect, and technical jargon, making it a challenging yet rewarding read that transcends the boundaries of the detective genre to offer a profound commentary on the human condition.

In this satirical farce, an eccentric and quick-witted man, referred to as the Maniac, infiltrates a police station where an anarchist railway worker's death is being investigated. The authorities claim the anarchist died by suicide, having jumped out of a window during an interrogation. However, the Maniac cleverly impersonates various officials, manipulates the policemen, and exposes the absurdities and contradictions in their stories, suggesting that the anarchist's death was not an accident but a cover-up of police brutality. The play uses sharp humor and slapstick to critique corruption and the misuse of power within the establishment, ultimately questioning the integrity of the police and the justice system.
