On a visit to Moscow in 1938, Sholokhov met Yevgenia Yezhova, wife of Nikolai Yezhov, the chief of police, and checked into a hotel room with her, unaware that the room was bugged. Yezhov heard the recording and attacked Yezhova. On 23 October 1938, Sholokhov met Stalin in the Kremlin to complain that he had been put under surveillance in Veshenskaya, but when Yezhov was summoned to explain, he claimed not to know why. They met again on 31 October: this time the officer who had been investigating Sholokhov was also summoned. He said his orders had come from Moscow, but Yezhov again denied giving the order. Sholokhov claimed that he completed the fourth and last volume of "And Quiet Flows the Don" and its sequel on 21 December 1939, the day when the USSR was celebrating what was supposedly Stalin's 60th birthday, and celebrated by opening a bottle of wine that Stalin had given him. He then wrote to Stalin to say how he had marked the special day.
