All that matters in a good mystery is the ENDING. You will suffer through endless pages of subtle clues, and even parts that take you no where if the ending is a “shocker”! Of course to get to that ending one must build the suspense throughout the book and give you characters you somewhat care about or you’ll stop before the “shocker”. Yet in the end the end is what counts when you say that was a great mystery book even if it actually was only just a couple of pages.
