"The third novel in Sartre's monumental Roads to Freedom series, Troubled Sleep powerfully depicts the fall of France in 1940, and the anguished feelings of a group of Frenchmen whose pre-war apathy gives way to a consciousness of the dignity of individual resistance — to the German occupation and to fate in general — and solidarity with people similarly oppressed." — Random House
