If a woman has a higher education diploma, it does not mean that she is smart enough. Dasha Vasilyeva once again went on about her friend Larisa and agreed to look after her cats, a mini pig and a crow chick while she was away. And now Dasha's house is just a zoo, the inhabitants of which do what they want. And in the detective agency "Tyukh-Plaza", which is managed by Colonel Degtyarev, work is in full swing. Sofya Petrovna Nikolaeva turned there with a request to investigate the circumstances of her husband Grigory's death. In the evening, he went to the bathhouse on their suburban plot, spent the night there in the recreation room, and did not wake up in the morning. The autopsy showed that his lungs were completely destroyed — this happens in the last stage of cancer. But no cancer cells were found. And soon their housekeeper Zina died. So her lungs were destroyed, too. And then ... then something began that could not be said in a fairy tale, nor described with a pen.
