The moon rose in silver splendor into an October sky strewn with pale clouds and brilliant stars. The clouds churned, a white-foam sea, and the moon was a vast, graceful clipper ship, its sails full of spectral light as it ran before the strength of the cold autumn winds. Pale light bleached each of the uncut stones on the nine-foot wall around Gentleman Johnny Marcone's estate, making edges sharper, shadows blacker, until it looked like a barrier made of gaping white skulls. Trees grew up thick on the other side of the wall, blocking the view of the interior, though no branches extended far enough to provide a way to climb over it.

"We've got to get over the wall," I said to the enormous, dark wolf beside me, keeping my voice low as we all crouched in the shadows of the bushes across the street from Marcone's estate. "There will be security on it. Maybe cameras, maybe infrared beams, maybe something else. I want you to find us a way past it." The wolf flickered her amber eyes toward me and made a soft, assenting growl. Then she simply turned and faded into the darkness, leaving five more furry, crouching shapes grouped around me.

The Alphas didn't exactly inspire confidence, but they had all managed to master enough rudimentary magic to transform themselves into very, very close approximations of wolves, at least. It was something.

Susan had parked the van on a hill leading up to Marcone's estate, and remained with it, in case we needed a quick getaway. When we'd arrived, a nude Tera West and five young people, three female and two male, had leapt out of the van, the Alphas hurriedly tumbling out of their robes.

"Hell's bells," I'd complained, "we're on a public street. Can you be something besides naked, here, people?"

Tera had smirked and, in a liquid shimmer, become a gaunt, dark wolf, a beast fully as large as Denton and his cronies had been, but with a narrower muzzle and cleaner proportions. Like Denton and his crew of Hexenwulfen, she kept the exact same shade and color of her eyes, even in wolfish form.

"Well?" I'd demanded of the others. "Let's hurry it up."

Georgia had slipped her lean body from her dark robe and melted in a few seconds into her wolf shape, then had quickly slipped past me to go to Tera. Billy had growled something under his breath as he shrugged out of his robe, catching one sleeve on his arm as he'd begun to change.

Billy-wolf had stumbled over the robe still hanging on to his forepaw, tripped, and tumbled onto the street with a whuff of expelled breath and a little whimper.

I'd rolled my eyes. Billy-the-wolf had snarled and struggled out of his robe, picked it up carefully in his teeth, like a large and particularly grumpy-looking Benji, and put it back in the van.

"Um," one of the other girls had said, a redheaded lass who filled out her robe a little too generously. "We're still a little new at this." She'd covered herself with her arms awkwardly, letting her robe fall from her shoulders as she whispered a little chant, and had become a rather round, hefty-looking she-wolf with dark auburn fur. She'd moved daintily to the edge of the cargo van and had minced, despite her weight, down to the street. The other two young people, a lanky, dark-haired boy and a scrawny girl with mouse-brown hair, had made the change and loped up the hill after Tera, and then we all had moved as quietly as we could to the rear of Marcone's estate.

Surrounded by a high stone wall, the property occupied an entire block, bounded on all four sides by individual streets. None of us had known the layout to Marcone's place, so we'd chosen to approach from the rear, on general principles of sneakiness. I hadn't thought it would be wise to walk in the front door, so I had dispatched Tera to find us a way in, while I'd remained behind with the Alphas.

I found myself tapping my fingers on my thighs as I crouched, restless. I soon realized that if I was tense, the would-be werewolves were twice as keyed up. The darkest-furred one, Billy, I thought, rose to his paws and started away, in the opposite direction from which Tera had gone. Georgia growled at him, Billy growled back, and the other male rose to follow him.

Great, I thought. I couldn't afford to let the Alphas wander off now, no matter how restless they were.

"Hey," I said quietly. "You can't go haring off now. If there's a way inside, Tera will find it."

The wolves all turned their heads, and their very human eyes, toward me.

Billy planted his paws stubbornly and growled.

"Oh, don't give me that," I snapped, glaring at him without meeting his eyes. "You promised you'd play this my way, Billy. This isn't a time to be messing around."

Billy's stance became less certain, and I beckoned all of them toward me. If I could keep them listening until Tera got back, I could at least be sure that they'd be around when I needed them. "Huddle up, everyone," I said. "I want to go over some things before we go in."

There was a brief silence, and then a crowding of furry, heavy bodies, and a snuffling of wet noses. Ten ears pricked up and rotated toward me, and ten bright, human eyes fastened upon me from lupine faces. I suppressed a sudden urge to say, "Good evening, class. I'm your teacher, Mr. Dresden," and instead put on my most serious expression.

"You all know what's at stake tonight," I said. "And that we could all get killed. We're going to be confronting a bunch of law-enforcement people who have gotten hold of some magic that's as black as anything I've ever seen, and are using it to turn themselves into wolves. They've lost control of the power they've grabbed. They're killing people, and if we don't stop them they're going kill a lot more. Especially me, because I know too much. I'm a danger to them.

"But I don't want that. I don't want anyone to get killed. Not us, and not them. Maybe they deserve it. Maybe not. The power they grabbed has turned into a drug for them, and they're not really in control of themselves anymore. I just don't think we'd be much different than them if we went in there planning to wipe them out. It isn't enough to stand up and fight darkness. You've got to stand apart from it, too. You've got to be different from it."

I cleared my throat. "Hell. I'm not good at this. Go for their belts, if you can, just like I did in the alley. Once their belts are off, they're not going to be as crazy, and maybe we'll be able to talk to them." I glanced up at the wall and back down. "Just don't get killed, guys. Do what you have to do to stay alive. That's your first priority. And if you've got to kill them to do it, then don't hesitate."

There was a chorus of growls from around me, led by the wolf Billy, but that was the great thing about being the only human being there—I was the only one who could talk. There wouldn't have been any arguments, even had they disagreed. Their enthusiasm was a little intimidating.

"If you are any louder, wizard," Tera's soft voice came from behind me, "we might as well walk through the front gate." I jumped and looked up to see Tera, naked and human, crouched down a few feet away.

"I wish you wouldn't do that," I hissed at her. "Did you find a way in?"

"Yes," she said. "A place where the wall has crumbled. But it is far for you to walk, around along the eastern wall, toward the front of the property. We must run if we are to get inside in time."

I grimaced. "I'm not in any shape to run anywhere."

"It would seem you have little choice. I also saw many streaks of light across the front gate. And there are black boxes with glass eyes every seventy or eighty paces. They do not see the crumbled place. It is a fortunate position."

"Cameras," I muttered. "Hell."

"Come, wizard," Tera said, crouching down on all fours. "We have no time to waste if you are to join us. The pack can cover the distance in moments, but you must hurry."
