Foucault's Pendulum

Blending history with gripping suspense, this international bestseller by Umberto Eco explores how a playful idea can spiral into deadly consequences. What begins as a literary joke soon turns into a chilling confrontation with belief, obsession, and power.

When a man claiming to have uncovered a secret Knights Templar plot approaches three skeptical editors, they decide to amuse themselves by inventing an elaborate conspiracy. Using fragments of occult lore and historical myths, they construct a fictional plan centered on a mysterious point of power linked to Foucault's Pendulum in Paris.

But as their invention begins to attract dangerous attention, the line between fiction and reality dissolves—and the joke takes a dark, life-threatening turn.
