A very dangerous woman : the lives, loves and lies of Russia's most seductive spy / Deborah McDonald, Jeremy Dronfield

An interesting perspective on Russia at time of the Revolution and afterwards, as well as a view of Europe before the Second World War, political intrigue and the involvement of well known figures such as H.G.Wells. Not a light read but worth it for background to history of the period told through the life of a woman who led a strange life.
