ended at a boarded-over doorway to what must have originally been a basement apartment like my own. He glanced around, tugged down a chain that looked like it had rusted flat to the wall beside the door, and opened it, disappearing within.
Crap. If this place had a threshold on it, I'd never be able to follow him inside. I'd just bang my metaphysical head against the doorway like a bird hitting a windshield. Never mind that if it had the proper kinds of wards, they could conceivably disintegrate my spiritual self, or at least inflict some fairly horrible psychic damage. I could wind up on the floor of my lab, drooling, transformed from professional wizard into unemployed vegetable.
Screw it. You don't do a job like mine by running away at any hint of danger.
I steeled myself and willed myself forward, following Grey Cloak.

CHAPTER
Fifteen
N o threshold, which was good. No wards, which was even better. Grey Cloak hadn't entered a living area—he'd entered Undertown.
Chicago is an old city—at least by American standards. It has been standing, in one form or another, since the French and Indian War, before the United States even existed. Being as Chicago is basically one giant swamp, from a strictly geographic point of view, buildings tended to slowly settle into the earth over years and years. The old wooden streets did the same, and new streets had to be built atop them in successive layers.
Wherever the ground isn't slow-motion mud, there's solid rock. Tunnels and cave systems riddle the area. The Manhattan Project had been housed briefly in such tunnels, before it got relocated to the middle of nowhere. Someone in the government had shown unaccountably good judgment in considering the notion that developing a freaking nuclear weapon smack in the middle of America's second-largest city qualified as a Bad Idea.
All of that had left behind an enormous labyrinth of passages, caves, half-collapsed old buildings, and crumbling tunnels seemingly ready to come thundering down at any moment. It was dark, human beings rarely went there, and as a result, Undertown had become a home, shelter, and hiding place to all kinds of nasty things—things no mortal, not even a wizard, had ever seen. Some of those things, in turn, had expanded some of the tunnels and caves, establishing jealously protected territories that never saw the face of the sun, never heard the whisper of wind. It's dark, close, cold, and intensely creepy down there. The fact that it was inhabited by things that had no love for mankind and potential radioactivity to boot didn't do much to boost its tourism industry.
Grey Cloak paced swiftly through a crack in the back wall of the building and into Undertown's tunnels. He grew even more indistinct as he did. I had to stay closer to him, and it cost me an increasingly greater effort of will to do so. Little Chicago hadn't accurately modeled Undertown, partly because there were no maps to be had of the place, and because taking samples to incorporate into the model would have been an act just shy of active suicide. Mostly, though, it hadn't happened because I had never considered doing so.
Through the translucent veil of earth and stone and brick, I could still see the real me standing over the city. My hand was still held out, but my fingers were trembling, and sweat beaded my forehead. Odd that I couldn't feel the strain on my body from here. I hadn't anticipated that. It was entirely possible that I might have continued on without ever realizing what the effort was costing me. It could kill my physical body, leaving me…
I don't know what. It might kill me outright. It might kill my body while stranding my mind here. It might bind my awareness into place like some sort of pathetic ghost.
Get tough, Dresden. You didn't take up this career to run at the first hint of fatigue.
I kept going—but all the same, I looked up to check on myself as often as I could.
Grey Cloak was not long in reaching his goal. He found a narrow cleft in a rock wall, slipped inside it, and then pressed his hands and feet against either wall on the inside of the cleft and climbed up it with rapid precision. Eight or nine feet up, it opened into a room with three walls of brick and one of earth—a partially collapsed basement, I assumed. There were a few creature comforts in it—an inflatable mattress
