A man with no memory wakes up on the deserted staircase of a gigantic building. Gradually he learns about his identity and mission: he is Petr Brok, a detective sent to rescue Tamara, the princess kidnapped by the ruler of the monstrous Mullerdom, the house of a thousand floors. Ohisver Muller is a ruthless tyrant with many faces, eyes and ears in the most remote corners of his empire. But a revolution is spreading through the floors. Yet Petr Brok soon realises that, parallel to his Mullerdom adventure, he is living another life into which he keeps drifting against his will. What is dream and what reality? What is the flickering light inside a skull he sees in the darkness? And what is Mullerdom, a nightmarish reality or a figment of a fevered imagination, an allegory of the capitalist world or a dystopian vision of the future? With its humanistic message and imaginative power, Weiss's The House of a Thousand Floors, first published in 1929, is a masterpiece of many genres, both unconventional and still contemporary, that has withstood the test of time for close to a century now.
