The Babylonian king Belshazzar arranged a feast. In the midst of revelry, a mysterious inscription appeared on the wall. The king was frightened and soon disappeared from the palace. The next day he was found dead at the city gates. The case was investigated by the prophet Daniel and his nephew Akiva. The collaboration of these two detectives was remembered by the reader from the story “Yoni and Shosh”. As a result of a complex but successful investigation, the identity of the organizer of the murder, the impossibility of punishing the perpetrators, and something else important became clear.
