The end of April, 1894. In Moscow, the wedding season is in full swing. On Krasnaya Gorka, every young lady wants to make it to the altar in time to be happy. Three brides die the night before their weddings for no apparent reason. And then the mysterious Club of Merry Bachelors publishes a scandalous manifesto. Mammas and the police chief of Moscow are furious. Alexey Pushkin is assigned the investigation. To find out what happened, he will have to take an extreme step: marry a wealthy bride. But what about Agata Kern? Perhaps this story wouldn’t have happened if she hadn’t overheard a strange conversation at the Klin station—when she was traveling to St. Petersburg with a rich fiancé.
