Waiting by the lift with a suitcase
In 1936, after Stalin walked out of his opera Lady Macbeth of Mtsensk and Pravda denounced it as 'Muddle Instead of Music', Shostakovich spent nights on his Leningrad landing beside the lift with a packed case, so the NKVD would arrest him there and not in front of his wife and daughter. Summoned to the Big House, he was told by his interrogator, Zakrevsky, to return on Monday with names. When he came back, Zakrevsky had himself been arrested, and Shostakovich was sent home. His survival came from the arbitrariness of the purge machinery, not from any choice he made.
