I frowned, wondering immediately why this door wasn't being firmly
guarded by at least a platoon of Army men. Half a dozen possible
answers flashed through my mind. The more recent maps might simply
have omitted this discarded and unnecessary door. It might be sealed
shut on the other side. The Army might have caught the spy already.
Somebody in authority might simply have goofed.
As I stood there, pondering these possibilities, the door opened and
the spy came out, waving a gun.
