The fictional world of Will Self is unlike any other.In The Quantity Theory of Insanity, we learn, amongst other things, the dark and terrible secret of Ward 9, why you are right to think that London is full of dead people and that each and every human being is caught up in a colossal balancing act between the sane and the insane ...The Quantity Theory of Insanity is acerbic, satirical, hilarious and, most of all, utterly unique in imaginative vision.
