I just realized we have a problem with this poll and it needs to be addressed. Mystery & Thriller are not the same thing. They cannot go together. Just like science fiction & fantasy cannot go together. Two separate categories and we've not yet had the vote to allow tow different categories to be combined.
I have to say, that this poll is invalid due to mystery/thriller which is invalid because they are different. I've read thrillers that are not mysteries and mysteries that are not thrillers. So they cannot go together as they are different.
I dare anyone to prove they are the same. You cannot because they are not. Sure, there can be some overlap, but as for being the same, no way.
