Writing many very good novels does not automatically make someone an easy subject for an autobiography. The important thing about any artist is what he creates, and if he happens to be a writer his process of creation is - to the onlooker - boring: scribble-scribble, with long intervals of broodiness before the next scribble-scribble. If the scribbler happens to be, in addition, a bit mad, or disagreeable in some surprising way, or wildly promiscuous, or a closet sadist or whatever, then an autobiographer has something to work with. But if he happens to be simply very nice .... well, it can be a bit of a problem. And Brian Moore was a much nicer man than most good writers.
