Private inspector Hável happens to travel on the train which is attacked at Biatorbágy. His attention is drawn to a suspicious man, and in the next few days he confirms that it was indeed him who committed the crime. Yet the police accuses not the lunatic Marschalkó but the communists. Summary justice is declared.
