“Then a thought hit me like a ton of slag. Arlene wouldn’t bother taking time in this hellhole to scribble her mark unless she had a damned good reason. Not just to point out the sphere—if she knew it was there, she’d have used it herself like a good soldier. The only logical conclusion was that the arrow pointed the way out of the nuclear plant—the way Arlene Sanders had already gone. Like Arne Saknussen, she marked her own trail for all who followed. So why hadn’t I found it? Same way Arlene missed the patio door: there had to be another hidden door nearby that I had missed. Third time’s the charm. The damned door couldn’t have been more than five feet from the one I had found. One good push and it was open, leading to a beautiful piece of straight, well-lit corridor that reached its end with a clean, massive metal door that had printed on it the welcome letters EXIT—obviously a holdover from the plant’s mundane days as a hangout for humans. Feeling bold and unstoppable, I walked right up to that door and discovered that it required a computer key card before it would bless the lonely traveler with an open sesame. Great. Now I could be miserable again.”
