The Master and Margarita
From the album “Drawings by Alexander Ivanov”

Getting playful in the bedroom, Natasha daubed Nikolai Ivanovich with cream and was herself stunned with surprise. The face of the respectable downstairs resident was puckered into a snout, and his hands and feet turned out to have hooves. Glancing at himself in the mirror, Nikolai Ivanovich howled desperately and wildly, but it was already too late.
