Is It Possible That Information Falls Into a Black Hole?

So is it possible that somehow when the book falls into the black hole its information is duplicated into the outgoing radiation and we get it that way? Well that's an interesting question. The problem with it is it's known in quantum mechanics that you cannot really duplicate information. You can't even at least within the usual rules of quantum mechanics save the situation by duplicating the information. On the other hand what if you could duplicate the information but nobody could ever in principle detect the fact that you duplicated the information. This is after all a thought experiment just so the audience
