your success rate at crossword puzzles in prose
And when you do manage to solve the crime yourself and then find that the ending of the book confirms your deductions, do you then feel obscurely disappointed? Does it increase or decrease your enjoyment of the book if you are able to work out the identity of the murderer before the end of the book?
Personally I tend to feel a bit let down. But when I read modern crime fiction I’m not merely mildly disappointed, I’m usually disgusted, because even when there is a puzzle to solve the solution is usually too obvious. For me it’s even more irritating when the identity of the murderer turns out to support the agenda that the writer is trying to push, something that happens all too frequently in modern crime novels.
