A simple phrase: “Don’t be nervous, everything will be fine” can instantly drive a person into rage. But it’s time for the old friend of Ivan Nikiforovich and Tanya Sergeeva to look for the fifth corner. Fyodor Volkov, the big head of the office, which it is better not to mention in vain, contacted a special brigade. He had a secret wife, Lida Popova. They hid the relationship so that no one could use Popova as leverage over Volkov. But one day Lida called her husband and asked him to urgently come to the village of Kosyukhino. Fyodor rushed to the call, but found Lida dead on the floor in an abandoned hut. At that moment, a noise came from the street, which forced Volkov to hide in the closet for some time. When he came out, he saw with horror that the body had disappeared without a trace. In order for information about the terrible incident to reach the “office,” Volkov turned to private investigators for help. Tanya and her colleagues began the investigation with enthusiasm. Sergeeva found everyone: both Lida and those who crossed her out of life. But all her ideals simply collapsed when she found out their names... Daria Dontsova is the most popular and sought-after author in our country, the favorite of millions of readers. More than 200 million copies of her books have been sold in Russia. Her work fills hearts and souls with light, optimism, joy, and confidence in tomorrow! “Dontsova is an incredible hard worker! I don’t know of any other writer who has worked so hard. I regard her with respect as an example of hard work as a writer. Women need psychological support and receive it from Dontsova. At one time I myself read several of Dontsova’s novels. It is read by very different people. And very busy business women who need to turn off their heads for a while, and housewives who have a 15-20 minute break between dropping off and picking up their children.” – Galina Yuzefovich, literary critic
