The novel “The Thunderstorm on the Spree” is the final part of the trilogy by Y.P. Dold-Mikhailik “And One Warrior in the Field,” which is published for the first time in Russian. Grigory Goncharenko, now a certain Fred Schultz, was active in the first post-war years in Germany and Italy, revealing the emerging pockets of neo-Nazism, which is again raising its head in Europe. A fascinating and lively written novel keeps the reader in suspense and attracts with its sincerity and psychological authenticity, and, most importantly, it is extremely modern, because the problems posed in it trouble the world today, having crossed the borders of Russia.
