No, I'm not talking about one of my favorite Elvis songs. That's a whole other blog. Suspicious Minds is something my muse and I have. We see conspiracies EVERYWHERE and it works so well for us. Let me explain.
Do you ever see a news segment about a furniture store in Washington D.C. exploding from a natural gas build up? Of maybe a perfectly healthy Mexican government official has a heart attack on the eve of a new law being passed?
My muse and I see conspiracies. We see the furniture store exploding because of a intel deal gone bad. We see the government official being assassinated because he opposed the law.
Be suspicious, in your story let your characters be suspicious. Let the reader wonder if what their reading is the real deal or is there something more sinister behind it. Then show it to them. Hide things from your characters and make them wonder about each other. They will react in some very telling ways.
Check out the news this weekend and see how many alternate endings there could be. Be suspicious. Be paranoid. See conspiracies. Be the person in the trench coat on the corner. Watching. Waiting. Then write.
