The loose series of detective stories featuring Jan Kanyza as Major Bohuslav continues with another story. As the title suggests, it is once again about murder, but not of an ordinary domestic animal, but of "two-legged cats": models, photographic models, and above all unsuccessful high school students, girls who are extremely charming but also unhappy, superficial, and egotistical, who only want to gain and take in life, whether it be love, prosperity, or money. With her frivolous and cynical approach to life, she managed to make many enemies, which ultimately proved fatal for her.
