If a woman has a diploma of higher education, that doesn’t mean she’s smart enough. Dasha Vasilyeva once again went along with her friend Larisa and agreed to take care of her cats, a mini-pig, and a fledgling raven while Larisa was away. Now Dasha’s house is simply a zoo, full of residents who do whatever they want. And at the detective agency “Tyukh-Plaza,” which is run by Colonel Degtyaryov, work is in full swing. There came to them Sofia Petrovna Nikolaeva with a request to investigate the circumstances of her husband Grigory’s death. In the evening, he went to the bathhouse on their country property, spent the night in the recreation room, and in the morning he didn’t wake up. The autopsy showed that his lungs were completely destroyed—such a thing happens in the final stage of cancer. But no cancer cells were found. Soon afterward, their housekeeper Zina also died. And her lungs were destroyed the same way. And then… then things started to happen that you can’t even describe—neither in a fairy tale nor with a pen.
