I was well under way with my last novel following a particular plot. I ran into a doctor that I know in Home Depot. He is a diver too and was in the special forces. I asked him what he was up to and he said, Deep, technical diving." I asked him how deep and he said 300 feet. I commented that was almost Newt Suit territory, then asked if it was a wreck. He paused, smiled and said, "Yeah, that's all I can say." This threw my mind into overdrive. What was an ex Navy Seal diving on that he couldn't discuss? something that the government had to disavow any knowledge of? This put a major twist into my book and set off a major subplot. Ideas are out there, everywhere.
