(Could be spoilers in this thread) A detective investigating the murders he committed; I realize this has been done before, what's your opinion on this particular twist? Anything I should avoid in order to make it more original? Any examples of this twist being done quite well, or quite poorly? What I've got planned for my plot is that the twist should divide the reader on whether to support the protagonist or not. He's kind of justified, but then again he's just betrayed my reader's trust after many thousands of words. Thanks for your thoughts.
