What if you no longer knew what you were doing at night?

The audiobook The Sleepwalker by bestselling author Sebastian Fitzek is a gripping psychological thriller—and one of the author’s most unsettling audiobooks: intense, dark, and packed with unexpected twists.

Leon Nader has suffered from severe sleep disorders since adolescence. As a sleepwalker, he even became violent during his nocturnal wanderings and had to undergo psychiatric treatment. Today, Leon believes he is cured—until one night, his wife disappears without a trace from the apartment they share. Has his illness returned?

To find out what he does while he sleeps, Leon straps a motion-sensor camera to his forehead. But what he discovers in the footage defies all imagination: his sleeping self opens a door that should not exist and descends into a dark world concealing a terrible secret.

This audiobook by Sebastian Fitzek—narrated, as always, by Daniel Nicolás—will grip you from the very first minute. Psychological terror, an unsettling atmosphere, and a plot constructed with devilish precision await you, keeping you hooked until the very end. Perfect for fans of psychological thriller audiobooks, tension-filled stories, and tales that will send shivers down your spine.
