I am completly new on this website, so sorry if I am asking something thats been answered before! Anyway, I wanted to know if any of you guys know a good book or some great tips on this. I think we have all tried it, we read a book and it turns out that a small detail which we don't at first consider important turns out to have a crucial role for the story. A good example I suppose is J.K Rowling's trick with Draco Malfoy and Severus Snape and Dumbledores death (genius twist btw!). It is as if the author somehow hides a very crucial detail in the book and that what I would like to get some tips on (or a good book) THanks in advance !
