The two books he mentioned in an earlier comment in that thread are Red Holocaust (a German-language book that doesn't appear to have been translated into English in my cursory look) and Mao: The Unknown Story by Jung Chang (which is basically a hit-piece on Mao).
Jung Chang's idea of citing multiple sources is asking the CIA, the State Department, the President, some USAID organizations, and a few CIA assets. Then deciding to just make stuff up anyway to make Mao into a comic book supervillain.
