Мафия 89. Nemesis

I tried to decipher the previous clues; how well I succeeded is up to you to judge. Bookworm -> a recently opened bookstore called "Bookworm" in the city of Frankfurt am Main -> which is a major city in Germany -> Göttingen and its `school` (Göttingen school), to which Emmy Noether belonged, who derived a theorem stating that every continuous symmetry of a physical system corresponds to a certain conservation law -> a conservation law in the profile of Yashchur. I didn't even consider IKEA furniture as a possible solution. GenIn -> an Indian domain offered to Russian businessmen -> Russian-Indian relations -> according to this article, India is the second largest market for the Russian defense industry -> Ryazan, which is a major military and industrial center of Russia -> Snowman
