Going through my archives of unfinished manuscripts, I found one I started about four years ago. It was about when a charismatic businessman with a shady past becomes president. My original notion was that a retired army intelligence general--who would be the main character--had been fired by the previous president. That had been an undercover operation to get the guy in good graces with the enemy so he could gather intelligence, and only the two of them, the general and the former president knew all that. I had Flynn in mind, obviously. He'd headed up the DIA (where I used to work) and had been fired for some reason or other. My fictional character was fired on trumped (no pun intended) up charges to set up his cover operation, and the new president doesn't know that and appoints him as National Security Adviser. That's as far as I got.
The problem was, every time I got a storyline going, something would happen in the news that trumped (okay, maybe that one was intended) my plot. Things were happening almost daily that I couldn't foresee and sure hadn't outdone. So I'd try to contrive something more outrageous than the current reality, and the next reality would step in to make mine look lame by comparison. So, I relegated the manuscript and my research material to the files of back-burner archives.
This is the first time I've noticed in which the real world makes for a more interesting and unbelievable read than anything I can dream up.
I'd like to hear from others who might have had similar setbacks in their story developments.
