The Organist at St. Vitus' Cathedral (1929)

The old organist unwittingly witnessed the suicide of an unknown man. Before his death, he handed him an envelope with money for his daughter Klara, who lived in the monastery. The organist did not report the case to the authorities, but hid the suicide's corpse in the cellar. Little did he know that he was being followed by his unscrupulous neighbor, a shoe shiner, who then blackmailed him with the threat of a murder charge.
