Hippo under mayonnaise. Dontsova D.A.

Of course, it is unpleasant to find out that a colleague came up with an offensive nickname “Hippo under mayonnaise”, but Tatyana Sergeeva has no time to be upset due to nonsense. Professor Alexei Burkin turned to the office of a special brigade: it seems that one of the family members pours a potent laxine doctor. The situation at first glance is stupid, most likely someone’s prank. According to the professor, in their family everything is kind to each other, and yet he needs to bring the attacker to clean water. Detectives decide to send Tanya to the house of Burkin under the guise of his relative from the Far East, Louise. Allegedly, she came to Moscow on business. It turns out in the house of a professor who is by no means a good relationship. The daughter -in -law Irina rushes at anger at all, and the second daughter -in -law - the confectioner Lyuba - on the contrary, is clumsy to nausea. And Sergeeva begins the investigation. A specialist in the searches of Timofei Volynov comes to Burkin. Having drunk the compote welded to Alexei, he loses consciousness. Who could poison him and why? The detectives of a special brigade find out that in childhood, Alexei’s wife was a black spot. This discovery allows them to reach an attacker. But... everything suddenly turns out to be completely wrong! In appearance, a slender and logical pyramid of evidence instantly collapsed and turned into ruins.
