First published in 1927, The Madonna of the Sleeping Cars, featuring the free-spirited heroine Lady Diana Wyndham, sold over 15 million copies worldwide.

From London to Berlin—with stops in Scotland and Russia—here are the mad adventures of the scandalous and brave Lady Diana Wyndham, as told by the prince Séliman, her secretary and confidant, as they voyage from one end of Europe to the other. A young, broke widow with a carefree and liberated heart, she pursues Varichkine, a Bolshevik commissioner in Berlin. Lady Wyndham needs his authorization to exploit the oilfields her deceased husband acquired before Russia became Soviet.

The Madonna of the Sleeping Cars is the unforgettable portrait of a young jetsetter (before her time) who navigates with ease through the just barely unveiled territories of psychoanalysis and revolutionary socialism.
