To judge the book solely on the basis of one essay of many is itself not only unreliable, but also bizarre. In fact Hitchen's review of Olivier Todd's biography is not nearly as derogatory of Malraux as you claim, and suggests an unreasonable level of hero worship on your part. The main charge that Malraux was a fantasist is hardly vitriol and it would have been more helpful if you had refuted some of the evidence given for it. I'm afraid writing "so much" and "even been Minister for Culture in France" doesn't really cut it. Writing "so well" is getting there, but very subjective, and not actually denied in the essay.
As for people being jealous of Malraux; that's a little petty, don't you think?
