« For me, as for many others, the reading of detective stories is an addiction like tobacco or alcohol. The symptoms of this are: Firstly, the intensity of the craving–if I have any work to do, I must be careful not to get hold of a detective story for, once I begin one, I cannot work or sleep till I have finished it. Secondly, its specificity–the story must conform to certain formulas (I find it very difficult, for example, to read one that is not set in rural England). And, thirdly, its immediacy. I forget the story as soon as I have finished it, and have no wish to read it again. If, as sometimes happens, I start reading one and find after a few pages that I have read it before, I cannot go on. » W. H. Auden, The Guilty Vicarage.
