Query: Dreadful

This has to be the worst biography I've ever read, hands down. What sort of editor would let this get published? Tolstoy pads this thing out to such an extent you want to pull your hair out. And the man has no humour whatsoever. Deadly dull prose, all the more horrifying when you consider the subject- Patrick O'Brian- took such care with HIS brilliant writing, and was himself a master prose stylist. Avoid at all costs. O'Brian needs someone to do him justice (and not a besotted fan either). What a biography it would be!
