My Idea of Fun by Will Self
When the young Ian Wharton first meets Mr Broadhurst, he is completely unaware of the influence he will come to exert over his life as ' The Fat Controller' - a constant companion and confidant and also the obese, erudite manifestation of Ian' s mental illness. As Ian' s idea of fun becomes increasingly extreme, the reader is taken to a place where morality is eroded by the dull grind of modernity and everything becomes admissable.
