A very short story of the "dog heart"? Who knows?

A professor of cooking and his assistant invented a very delicious dish, the main ingredient of which is a dog’s heart. And here they go with this dish to Italy for a culinary reality show very popular in Europe and become its winners. The recipe is tried to buy from a professor, trick, steal, different political forces of the world, but he keeps it secret. At this time in Russia, the Bolsheviks come to power, the leader of which Vladimir Lenin, asks the professor to prepare this dish for him, and sends him an agent of the CCHR Sharikov with the task to find out the recipe. The professor and his assistant unraveled the Bolshevik agent in Sharikov, killed him, removed his heart from his chest and prepared for Lenin the place of a dog. Lenin eats his heart and begins a policy of terror in the country. The professor and his assistant open a restaurant in the Korean quarter of Paris but in the 1930s return to the USSR where they immediately get into the GULag.
