His masterpiece, The Master and Margarita, is just that, a masterpiece. A parody of the Soviet society where Stalin is the Devil, Bulgakov's third wife is the bewitching Margarita, and Bulgakov himself is represented by the Artist. Nothing is what it seems and Moscow is turned upside down.
Another interesting read by Bulgakov is the novella The Fatal Eggs. The book can be classified as a laugh-out-loud-satire of the 1917 revolution and the new Soviet society that followed it.
"But would you kindly ponder this question: What would your good do if
evil didn't exist, and what would the earth look like if all the shadows
disappeared? After all, shadows are cast by things and people. Here is the
shadow of my sword. But shadows also come from trees and living beings.
Do you want to strip the earth of all trees and living things just because
of your fantasy of enjoying naked light? You're stupid."
— Mikhail Bulgakov (The Master and Margarita)
