“A bored housewife, a husband who married her for show, and a stupid boy who is full of himself because he is dating a Swiss woman.” The words of Inspector Tůma sound like they’re from a European melodrama, but in fact they come from a Czechoslovak crime story. A pair of detectives, counterfeit medicine, the high-society setting of a Karlovy Vary hotel, and Oldřich Nový as the aging hotel manager Kraus.
