No 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 and sleeping bag, a lantern, a miniature barbecue next to a heavy paper bag of charcoal, and several cardboard boxes that contained supplies.
Grey Cloak slipped a heavy grate over the hole he'd just climbed up, and weighted it down with several stones the size of cinder blocks. Then he opened a box, unwrapped a pair of those meal-replacement bars that people use to punish themselves when they think they're overweight, ate them, and emptied a plastic bottle of water. Critical information, there. Glad I was risking my metaphysical neck to pick up vital clues like this.
I checked up over my shoulder. My face had gone white and ran with sweat.
I expected Grey Cloak to turn in, but instead he turned the lantern down low, opened a second box, withdrew a plaque the size of a dinner plate, and laid it down on the floor. It was a simple wooden base, inset with a ring of some reddish metal, probably copper.
Grey Cloak pressed a fingernail against one of his gums, and when he withdrew it his fingertip glistened with blood that looked far more solid and real than the person it had come from. He touched it to the circle and began a low chant I did not recognize.
A faint mist swirled up within the copper circle, and through the spell I could see the raw magic forming itself into a pattern, a vortex that vanished beneath the plaque.
A second later, the mist resolved itself into a figure, in miniature, a vaguely humanoid shape wearing a heavy cloak and cowl that hid any possible details of appearance.
Except that I'd seen him before—or at least someone who dressed exactly like him.
The last time I'd seen Cowl, he'd been caught in the unbelievably savage backlash of an enormous power-summoning spell called a Darkhallow, It would have been impossible for the man to have survived that spell. There was no way, no way in hell that he'd lived through it. This couldn't be the same person.
Could it?
Surely it had to be someone else. The Ringwraith look was hardly uncommon among those who fancied themselves dark wizards of one kind or another, after all. It could just as easily be someone else entirely, someone not at all connected to Cowl or my theoretical Black Council.
On the other hand, Cowl had been the person whose actions had tipped me off to the possibility of the Black Council to begin with. Could he have been a part of the Circle that Grey Cloak had mentioned? After all, I dropped a freaking car onto Cowl's head, and he'd hardly blinked at it. If he'd been that well protected, could he have survived the wild energies of the disintegrating Darkhallow?
Worse, what if he hadn't? What if he was one of a set of people just as crazy and dangerous as he had been?
I started feeling even more nervous.
"My lord," Grey Cloak said, bowing his head. He left it that way;
There was a long moment of silence before Cowl spoke. Then he said, "You have failed."
"I have not yet succeeded," Grey Cloak replied with polite disagreement. "The curtain has not fallen."
"And the fool with you?"
"Still ignorant, my lord. I can preserve or dispose of him as you see fit." Grey Cloak took a deep breath and said, "He has gotten the wizard involved. There is some sort of vendetta between them, it would seem."
The little mist figure made a hissing sound. "The fool. There is not enough profit in Dresden's death to jeopardize the operation."
"He did not consult me on the matter, my lord," Grey Cloak said with another bow of his head. "Had he done so, I would have dissuaded him."
"And what followed?"
"I attempted to remove him along with the last of the culling."
"Dresden interfered?"
"Yes."
Cowl hissed. "This changes matters. What precautions have you taken?"
"I was not followed in flesh, my lord; of that I am certain."
Cowl held up a miniature hand for silence, a gesture that looked, somehow, stiff and pained. Then his hood panned around the room.
The figure's gaze met mine, and hit me like a literal, physical blow, a swift jab in the chest.
"He is there!" Cowl snarled. The misty figure turned to face me and lifted both hands.
An odd, cold pressure hit me like a wave and pushed me back several feet before I could gather up my will and exert pressure in return, coming to a stop several feet away from Grey Cloak and Cowl.
Cowl's hands clenched into claws. "Insolent child. I will rip your mind asunder."
I snarled at him and planted my insubstantial feet. "Bring it, Darth Bathrobe!"
Cowl screamed at me. He spoke a word that resonated in my head and thundered through the hazy confines of Grey Cloak's hideaway. Though I had braced myself to gather my will and pit it against his, his next strike hammered into me like a freight train. I could no more have resisted it than I could have stopped an ocean tide, and I felt it throwing me back and away.
In that last second before I was banished, I reached out with all the strength I had left, focusing on Grey Cloak, pouring everything I had into the spell to grant me a clear view of his face. I got it, for the barest instant, the face of a man in his mid-thirties, tall and lean and wolfish.
And then there was a geyser of scarlet pain, as if someone had seized both halves of my skull and torn it into two pieces.
Darkness followed.
