I don't find greed amusing and I don't find reading about greed amusing, so this book didn't do it for me.
It is clear that the author found writing this book cathartic and therapeutic, but it has led him to try to put everything he knows and has experienced into this one volume - he would have done better to have been more selective. Whilst the sections about the workings of the City are interesting and well written, in an apparent attempt to appear laddish, those sections dealing with the main protagonist, a thinly disguised version of Anderson himself, are just too propped full of every possible analogy, metaphor, simile and cliché to be pleasurable reading. His thesaurus must be in tatters!
Perhaps the timing of reading is important - with the banking crashes we have all become more aware of how the Square Mile works, and this book is therefore less effective.
