While I'm at it, I wish to raise another gripe of mine -- besides series of novels going on longer than they merit. That is when authors break a kind of pact I think they (should) have with readers.
The pact is that as readers we will more or less suspend disbelief and go along with the story, even enjoy being led astray as we go, but NOT be suddenly tricked in a kind of "Ha, Ha, I sure made an ass out of you" revelation in the last two pages.
I don't mean a solution to the mystery that you never suspected, but being told at the end that the whole thing was actually someone's nightmare, or the ravings of an inmate in an asylum, or the last thoughts (before the killer returns) of a murder victim who you have been continually led to believe was going to escape, etc.
Two such that come to mind are Shutter Island by Dennis LeHane (& movie w/ Leaonard Decaprio) and the more recent Sister by first time author Rosamund Lupton. Both novels are exceptionally well written page turners which makes it doubly irritating to get to the ending which is a: "WHAM! Ha! Ha! Fooled Ya! -- Did you really believe that story? -- Well, maybe it happened as I told it--or maybe some of it, or maybe none. Now I can tell you that ya got all worked up over absolutely nothing. HA! HA! The jokes on you!"
Perhaps they think such an ending moves them out of the mystery genre (with its pact?) into something more Shakespearian in level of tragedy -- or something.
Does this bother you? I know lots of people loved the two mentioned novels, so maybe I shouldn't be upset.
[Well, I'm the one going around giving negative awards for improbabilities and refusing to read books where I expect to see too many of them.
[I agree that an author who betrays readers is a jerk. I don't want to read about angels, miracles, protective spirits, and sprites unless I'm reading something that's obviously fantasy.
[What do you think? Write and tell this little bit of the world.]
