The police witnesses cannot agree on the licence plate, but the poet Jaroslav Nerad, who saw it, has only written a surreal poem. Inspector Mejzlík reads its images as the shapes of digits: a swan's neck for 2, breasts for 3, drum and cymbals for 5. This gives plate 235 and catches the driver, showing that an imaginative witness can record accurate perception in a form literal witnesses miss.
In 'Footprints', a man finds footprints in fresh snow that stop dead in the middle of an empty street, and he reports them to the police. Inspector Bartošek refuses to investigate: no one is harmed and no law is broken, so the anomaly is outside the police's remit. Institutions of knowledge are built to process crimes, not wonders, and people must live with inexplicable events rather than force them into a case file.
In 'The Last Judgment', the murderer Kugler dies and stands before a heavenly court. God appears only as a witness, not as judge. God explains that because He knows everything about Kugler, including his childhood, his loves and his motives, He could not condemn him. Judgment is therefore a human act that depends on partial knowledge, and complete understanding dissolves the ability to punish.
In 'Professor Rouss's Experiment', a psychologist gives a suspect a rapid free-association test, and the suspect's spontaneous responses reveal where he buried a body. When a journalist takes the same test, every answer is a newspaper cliché. Rouss diagnoses him as a mind made entirely of stock phrases. Unreflective responses reveal what a person actually carries inside, whether that is a hidden crime or no private thought at all.
