The perpetrator was most likely a student named F. Kirchner. Cimrman was a police inspector in Vienna's 4th district at the time, and the school principal turned to him when all educational measures had failed. Six police officers followed the suspect for three days, but to no avail. Cimrman therefore decided to influence Kirchner in a different way: he wrote a play about the theft, which was staged by the police department's drama club as a compulsory school performance. The author expected that seeing the suffering of the teacher, principal, and inspector during their futile investigation would lead the culprit to regret his actions and confess. However, the stubborn boy, the son of a nun, was not moved.
