The rolling hills and meadows of Maine seemed a world away from the fume-choked dangers of Chicago. Only the occasional big truck out on the two-lane highway, grinding up through the gears, hammering down the long gradients, growled out an intrusive threat. But behind the house and far away from the road: that was safe.

Just a carefully cleared path up into the woods where generations of local children have processed with the solemn innocence of the young, taking with them their dear departed pets for burial. A sad place maybe, but safe. Surely a safe place. Not a place to seep into your dreams, to wake you, sweating with fear and foreboding.
