man myself)and it's difficult to stomach an "even-handed" (i.e., non-judgemental) account of his behavior during and after WWII, but, solely from the perspective of this work being a window into the relationship of, arguably, the two foremost French thinkers of the twentith century (and please don't throw-up Foucault, Derrida and crew against C & S) - it has considerable value and is worth the read.
The friendship and then the falling out between Sartre and Camus is more than biography and tells the story of the Cold War in story book dialectical form. This account brings this self-reflective history to light, beginning with the period of the War, the Vichy regime and the Resistance, then the postwar euphorias of both authors as they become public intellectuals par excellence. Their friendship and vanguard solidarity conceals hidden differences, and as the Cold War gets into gear the divergence of 'lefts' finds its exemplars. It would seem sad in one way, and yet this encounter and division produced the dialectic needed to confront the legacy of Communism and capitalism in collision, as if a fated broil. Within a few years all the issues, later the stuff of endless discourse, were tabled, and the stakes clear til the end in 1989.
