Like fate haunts the residents of the town of Molena Point. Here again atrocities are happening - mysterious murders, which people, limited by only five senses, are not able to solve. Once again, detective cat Gray Joe and his friend Dulcie come to the aid of the bipeds. But now they have an assistant: in the eyes of people - a cute, clueless kitten, and in Joe's opinion - a future genius of cat detective. The three of them solve human crimes, as always, remaining in the shadows: after all, if the police are given clues to the solution and anonymously report the evidence, then they act completely independently and even show glimpses of intelligence.
