They have read your novel … and they said only one thing, that, unfortunately, it is not finished. So I wanted to show you your hero. He has been sitting here for about two thousand years, sleeping, but, when the moon is full, he is tormented, as you see, by insomnia. And it torments not only him, but his faithful guardian, the dog. If it is true that cowardice is the most grave vice, then the dog, at least, is not guilty of it. The only thing that brave creature ever feared was thunderstorms. But what can be done, the one who loves must share the fate of the one who is loved.
— Mikhail Bulgakov
