May Bride

Middle-aged men are dying in Liběšín, Central Bohemia. They know each other intimately, but neither of them knows why anyone would want to hurt them. And neither does private investigator Tara. Is it a deranged psychopath killing, or someone who knows exactly what he's doing? What does the ominous message from the May Bride mean? Is it a real person? Is that a clue to the solution? Or just a ploy to distract attention?
