He knew we were following a Halloweener, and as we trailed him I managed to intellectualize what the Old One picked up by instinct alone. The lack of spectators in my neighborhood meant that either nothing was going on, or people had been frightened back into their homes. The Halloweeners had obviously stationed lookouts in various places who then tipped Charles and the troll to my arrival. The lookouts took off, their role in the events finished, and I had managed to cut across the trail left by one of them.
