Who reads tales as 'The Tell Tale Heart' or 'The Black Cat...' can be taken by the feeling that there isn't, in the story itself, fixed points. In fact, few people indicate that the main character, who tells us (his) story, or is presented in a delusion that mistook a supernatural experience, or have an experience so amazing, so terrifying, that upset his judgment. This uncertainty is pure magic - literary magic -, wizard thing indeed. And it is also the purest Edgar Allan Poe. Innovator of horror stories, master and main source of romantic gothic american - and one of the main authors of the genre in world literature - he left us powerful stories and influenced many contemporary writers, as indeed is mentioned in this book.
