John Layeville expected history to remember him as the man who unlocked the secret of time travel. Instead, a disastrous experiment turned him into the most infamous prisoner on Earth, sealed inside an enormous swinging pendulum and displayed as a warning to anyone who dared challenge accepted science. What begins as a cruel sentence soon becomes something no one can explain. Years pass, then centuries, yet the prisoner remains alive while generations come and go around him.
Pendulum unfolds through Layeville’s remarkable journal, allowing listeners to witness history from an extraordinary viewpoint. Empires fade, technology reshapes civilization, robots inherit humanity’s work, and even they prove no more permanent than their creators. Unable to escape, Layeville becomes the only observer who watches Earth’s future from a single moving prison. Bradbury and Hasse expand the story from personal tragedy into an astonishing vision of deep time while never losing sight of the man at its center. Every new age leaves listeners wondering whether the pendulum will continue its endless arc—or whether something beyond imagination will finally bring it to a halt.
