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 Box Man" is a surreal narrative about a man who chooses to live as a homeless individual, inside a box, in Tokyo. The protagonist, a former doctor, narrates his experiences and observations from within the box, and the narrative often blurs the line between reality and hallucination. The book is a philosophical exploration of identity, anonymity, and the nature of existence, challenging the reader's perception of what it means to be an individual in society.
