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.

This novel follows three intellectual friends who work at a small publishing house. As a joke, they start inventing a conspiracy theory about a secret society that has been manipulating world events for centuries. However, as they delve deeper into their own fabrication, they begin to lose sight of what's real and what's not. Their lives take a dangerous turn when actual secret societies believe they hold the key to a universal secret and will stop at nothing to obtain it.
