The answer to the question: What is the last name of Raisa's husband's superior? is inside the article: In 1933, a child orphaned during the Ukrainian Holodomor runs away from his orphanage and is taken in by a Red Army unit and adopted by its kindly commander, who gives him the name Leo Demidov. In 1945, now a sergeant with the unit, Leo  becomes an icon across the Soviet Union when he is photographed planting the Soviet flag atop the Reichstag during the Battle of Berlin. He becomes a Hero of the Soviet Union. In 1953, Leo, now married to Raisa and living in Moscow, is a captain in the Ministry of State Security, commanding a unit tasked with tracking down and arresting dissidents. They arrest a veterinarian, Anatoly Brodsky, and during the arrest, one of Leo's subordinates, the cowardly but ambitious Vasili Nikitin, shoots a farmer, Semyon Okun, and his wife in whose barn Brodsky has been hiding, orphaning their two young daughters. Angry, Leo strikes Vasili, who harbours growing resentment against Leo and the other officer in the unit, Alexei Andreyev; all three were in Berlin together in 1945. Vasili is in charge of Brodsky's interrogation and execution, and one of the names he gives to their superior, Major Kuzmin, is that of Raisa, a primary school teacher, several of whose colleagues have recently been arrested for dissident views. Kuzmin orders Leo to investigate his own wife. Meanwhile, Alexei's young son, Jora, is found dead near a railway yard. Although the initial pathology report shows injuries consistent with torture, the surgically precise removal of organs, and drowning, the authorities declare that he was hit by a train, as Stalin has decreed that murder is a capitalist disease; there is no murder in a communist paradise. Alexei is forced to accept the official conclusions to save himself and the rest of his family., can you guess it ?
A:
Kuzmin
