After writing a letter to Soviet government, requesting permission to emigrate, Bulgakov received a personal telephone call from Stalin and was employed as an assistant producer with the Moscow Arts Theatre. He adapted classics for the stage. During the late 1930s he was librettist and consultant at Bolshoi Theatre. However, Stalin's favour protected Bulgakov only from arrests and executions, but his writings remained unpublished. In Black Snow, a Theatrical Novel , Bulgakov described his love-hate relationship and took a revenge on Stanislavsky for the failure of his play A Cabal of Hypocrites , produced under the title Molière . In one scene Louis XIV, the Sun King, says: "Then hear this: my author is oppressed. He is frightened. I will show kindness to anyone who forewarns me of whatever danger imperils him... The ban is lifted. You may stage Tartuffe ." The Last Days was performed first in 1943 under the title Pushkin . Bulgakov's stage version of Gogol's Dead Souls had a modest success.
