Billy held the pizza while I drew the chalk circle on the ground, back in the alley. "Harry," he said, "how is this supposed to work exactly?"

"Hang on," I said. I didn't quite complete the circle, but took the pizza box from him. I opened it, took out one piece, and put it down in the middle of the circle on a napkin. Then I dabbed a bit of blood from the corner of my mouth where the girl had slugged me onto the bottom of the piece of pizza, stepped back, and completed the circle without willing it closed.

"Pretty simple," I said. "I'll call the faerie in close to the pizza there. He'll smell it, jump on it, eat it. When he does, he'll get the bit of my blood, and it will be enough energy to close the circle around him."

"Uh-huh," Billy said, his expression skeptical. He took out a second piece and started to take a bite. "And then you beat the information out of him?"

I took the piece out of his hand, put it back in the box, and closed it. "And then I bribe the information out of him. Save the pizza."

Billy scowled at me, but he left the pizza alone. "So what do I do?"

"Sit tight and make sure no one else tries to pop me while I'm talking to Toot-toot."

"Toot-toot?" Billy asked, lifting an eyebrow.

"Hell's bells, Billy, I didn't pick the name. Just be quiet. If he thinks there are mortals around he'll get nervous and leave before I can snare him."

"If you say so," Billy said. "I was just hoping to do more good than to deliver pizza."

I raked my fingers through my hair. "I don't know what you could do yet."

"I could track those three in the picture you showed me."

I shook my head. "Odds are they just got into a car and left."

"Yeah," he said, some forced patience in his voice. "But if I get their scent now, it might help me find them later on."

"Oh," I said, feeling a bit stupid. Okay, so I hadn't considered the whole shapeshifting angle. "Fine, if you want to. Just be careful, all right? I don't know what all might be prowling around."

"Okay, Mom," Billy said. He set the pizza box on top of a closed trash can, fell back down the alley, and vanished.

I waited until Billy had gone to find a nice patch of shadows to step into. Then I closed my eyes for a moment, drawing up my concentration, and began to whisper the faerie's Name.

Every intelligent being has a Name, a specific series of spoken sounds linked to its very being. If a practitioner knows the Name of something, knows it in every nuance and detail of pronunciation, then he can use that Name to open a magical conduit to that being. That's how demons get summoned to the mortal world. Call something's Name and you make contact with it - and if you're a wizard, that means that you can then exercise power over it, no matter where in the world it is.

Controlling an inhuman being via its Name is a shady area of magic, only one step removed from taking over the will of another mortal. According to the White Council's Seven Laws of Magic, that's a capital crime - and they make zero-tolerance policies look positively lenient.

Given how much the Council loves me, I'm a tad paranoid about breaking any of the Laws of Magic, so while I was calling the faerie's Name, I put only the tiniest trickle of compulsion into it, just enough to attract his unconscious attention, to make him curious about what might be down this particular alley. I whispered the faerie's Name and stood in the shadows, waiting.

Maybe ten minutes later, something made from a hummingbird and a falling star spiraled down from overhead, a flickering ball of blue-white light. It alighted on the ground, the light dimming to a luminous sheen over the form of a tiny faerie, Toot-toot.

Toot stood about six inches tall. He had a mane of dandelion-fluff hair the color of lilacs and a pair of translucent dragonfly wings rising from his shoulders. Otherwise he looked almost human, his beauty a distant echo of the lords of Faerie, the Sidhe. On his head he wore what looked like a plastic Coke bottle cap. It was tied into place with a piece of string that ran under his chin, and his lilac hair squeezed out from beneath it all the way around, all but hiding his eyes. In one hand he carried a spear fashioned from a battered old yellow Number 2 pencil, some twine, and what must have been a straight pin, and he wore a little blue plastic cocktail sword through another piece of twine on his belt.

Toot landed in a cautious crouch near the pizza, as though streaking in like an errant shot from a Roman candle might not have alerted anyone watching to his presence. He tiptoed in a big circle around the piece of pizza, and made a show of looking all around, one hand lifted to shade his eyes. Then he raised his arm into the air, balled up a tiny fist, and pumped it up and down a few times.

Immediately, half a dozen similar streaks of glowing color darted down out of the air, each one a different color, each one containing a tiny faerie at its center. They alighted more or less together, and every one of them was armed with a weapon that might have been cobbled together from the contents of a child's school box.

"Caption!" Toot-toot piped in a shrill, voice. "Report!"

A green-lit faerie beside Toot snapped to attention and slapped herself on the forehead with one hand, then turned sharply to her left and barked, "Loo Tender, report!"

A purple-hued faerie came to attention as well and smacked himself in the head with one hand, then turned to the next faerie beside him and snapped, "Star Jump, report!"

And so it went down the line, through the "Corpse Oral," the "First Class Privy," and finally to the "Second Class Privy," who marched up to Toot-toot and said, "Everyone's here, Generous, and we're hungry!"

"All right," Toot-toot barked. "Everyone fall apart for messy!"

And with that, the faeries let out shrill hoots of glee, tossed aside their weapons and armaments, and threw themselves upon the piece of pizza.

As soon as the little faeries started eating, the magic circle snapped closed around them with a hardly audible pop as it sprang into place. The effect was immediate. The faeries let out half a dozen piercing shrieks of alarm and buzzed into the air, smacking into the invisible wall of the circle here and there, sending out puffs of glowing dust motes when they did. They fell into a panicked spiral, around the inside of the circle, until Toot-toot landed on the ground, looked up at the other faeries, and started shouting, "Ten Huts! Ten Huts!"

The other faeries abruptly came to a complete stop in the air, standing rigidly straight. Evidently, they couldn't do that and keep their little wings going at the same time, because they promptly fell to the alley floor, landing with a half-dozen separate «ouches» and as many puffs of glowing faerie dust.

Toot-toot recovered his pencil spear and stood at the very edge of the closed circle, peering out at the alley. "Harry Dresden? Is that you?"

I stepped out from my hiding spot and nodded. "It's me. How you doing, Toot?"

I expected a torrent of outraged but empty threats. That was Toot-toot's usual procedure. Instead, he let out a hiss and crouched down in the circle, spear at the ready. The other tiny faeries took up their own weapons and rushed to Toot-toot's side. "You can't make us," Toot said. "We haven't been Called and until we are, we belong to ourselves."

I blinked down at them. "Called? Toot, what are you talking about?"

"We're not stupid, Emissary," Toot-toot said. "I know what you are. I can smell the Cold Queen all over you."

I wondered if they made a deodorant for that. I lifted my hand in a placating gesture. "Toot, I'm working for Mab right now, but it's just another client, okay? I'm not here to take you anywhere or make you do anything."

Toot planted the eraser end of his spear on the ground, scowling suspiciously up at me. "Really?" he demanded.

"Really," I said.

"Promise?"

"Promise."

"Super duper double dog promise spit swear?"

I nodded. "Super duper double dog promise spit swear," I repeated gravely.

"Spit!" Toot demanded.

I spat on the ground.

"Oh. Well, then," Toot said. He dropped his spear and darted over to the pizza, much to the consternation of the other little faeries, who let out piping shrills of protest and then followed him. The piece of pizza didn't last long. It was like watching one of those nature shows, where the piranha devour some luckless thing that falls in the water - except here there were glittering wings and motes and puffs of glowing, colorful dust everywhere.

I watched, frowning, until Toot-toot flopped onto his back, his tummy slightly distended. He let out a contented sigh, and the other faeries followed suit.

"So, Harry," Toot said, "who do you think is going to win the war?"

"The White Council," I said. "The Red Court's got no depth on the bench and nothing in the bullpen."

Toot snorted and flipped his plastic bottle-cap helm off his head. His hair waved around in the breeze. "Just because they don't have any cows doesn't mean that they won't win. But I don't mean that war."

I frowned. "You mean between the Courts."

Toot nodded. "Yeah."

"Okay. What's with the armor and weapons, Toot?"

The faerie beamed. "Neat, huh?"

"Highly scary," I said gravely. "But why do you have them?"

Toot folded his arms and said, with all the gravity that six inches of fluff and pixie dust can muster, "Trouble's coming."

"Uh-huh. I hear the Courts are upset."

"More than just upset, Harry Dresden. The drawing of the wyldfae is beginning. I saw some dryads walking with a Sidhe Knight from Summer, and a canal nereid climbed up out of the water a couple of blocks over and went into a Winter building."

"Drawing of the wyldfae. Like you guys?"

Toot nodded and propped his feet up on the legs of the Star Jump, who let out a surprisingly basso belch. "Not everyone plays with the Courts. We mostly just do our jobs and don't pay much attention. But when there's a war on, the wyldfae get Called to one side or another."

"Who picks which way you go?"

Toot shrugged. "Mostly the nice wyldfae go to the Warm Queen and the mean ones go to Cold. I think it's got something to do with what you've been doing."

"Uh-huh. So have you been doing Warm or Cold things?"

Toot let out a sparkling laugh. "How should I remember all those things?" He patted his stomach and then rose to his feet again, eyes calculating. "Is that a pizza box you have there, Harry?"

I held the box out and opened it, showing the rest of the pizza. There was a collective «Ooooo» from the faeries, and they all pressed to the very edge of the circle, until it flattened their little noses, staring at the pizza in fascinated lust.

"You've sure given us a lot of pizza the past couple of years, Harry," Toot said, with a swallow. He didn't look away from the box in my hands.

"Hey, you gave me a hand when I needed it," I said. "It's only fair, right?"

"Only fair?" Toot spat, outraged. "It's ... it's ... it's pizza, Harry."

"I'm wanting some more work done," I said. "I need information."

"And you're paying in pizza?" Toot asked, his tone hopeful.

"Yes," I said.

"Wah-hoo!" Toot shouted and buzzed into the air in an excited spiral. The other faeries followed him with similar carols of happiness, and the blur of colors was dizzying.

"Give us the pizza!" Toot shouted.

"Pizza, pizza, pizza!" the other faeries shrilled.

"First," I said, "I want some questions answered."

"Right, right, right!" Toot screamed. "Ask already!"

"I need to talk to the Winter Lady," I said. "Where can I find her, Toot?"

Toot tore at his lavender hair. "Is that all you need to know? Down in the city! Down where the shops are underground, and the sidewalks."

I frowned. "In the commuter tunnels?"

"Yes, yes, yes. Back in the part the mortals can't see, you can find your way into Undertown. The Cold Lady came to Undertown. Her court is in Undertown."

"What?" I sputtered. "Since when?"

Toot whirled around in impatient loops in the air. "Since the last autumn!"

I scratched at my hair. It made sense, I supposed. Last autumn, a vengeful vampire and her allies had stirred up all sorts of supernatural mischief, creating turbulence in the border between the real world and the Nevernever, the world of spirit. Shortly after, the war between the wizards and the vampires had begun.

Those events had probably attracted the attention of all sorts of things.

I shook my head. "And what about the Summer Lady? Is she in town?"

Toot put his fists on his hips. "Well, obviously, Harry. If Winter came here, Summer had to come too, didn't it?"

"Obviously," I said, feeling a little slow on the uptake. Man, was I off my game. "Where can I find her?"

"She's on top of one of those big buildings."

I sighed. "Toot, this is Chicago. There are a lot of big buildings."

Toot blinked at me, then frowned for a minute before brightening. "It's the one with the pizza shop right by it."

My head hurt some more. "Tell you what. How about you guide me to it?"

Toot thrust out his little chin and scowled. "And miss pizza? No way."

I gritted my teeth. "Then get me someone else to guide me. You've got to know someone."

Toot scrunched up his face. He tugged at one earlobe, but it evidently didn't help him remember, because he had to rub one foot against the opposite calf and spin around in vacant circles for ten whole seconds before he whirled back to face me, the nimbus of light around him brightening. "Aha!" he sang. "Yes! I can give you a guide!" He jabbed a finger at me. "But only if that's all the questions, Harry. Pizza, pizza, pizza!"

"Guide first," I insisted. "Then pizza."

Toot shook his arms and legs as though he would fly apart. "Yes, yes, yes!"

"Done," I said. I opened the pizza box and set it on top of a discarded crate nearby. Then I stepped over to the circle, leaned down, and with a smudge of my hand and an effort of will broke it, freeing the energies inside.

The faeries chorused several pitches and variants of "Yahoo!" and streaked past me so quickly that they left a cone of wild air behind them, tossing my unruly hair and scattering lighter pieces of garbage around the alley. They tore into the pizza with much the same gusto they'd used on the one piece earlier, but there was enough of it now to keep them from mangling it in mere seconds.

Toot zipped over to hover in front of my face and held out his little palm. A moment later, something that looked like an errant spark from a campfire whirled down and lighted on his palm. Toot said something in a language I couldn't understand, and the tiny light pulsed and flickered as though in response.

"Right," Toot said, nodding to the light. I peered more closely at it, and could just barely make out a tiny, tiny form inside, no larger than an ant. Another faerie. The light pulsed and flickered, and Toot nodded to it before turning to me.

"Harry Dresden," Toot-toot said, holding out his palm, "this is Elidee. She's going to pay me back a favor and guide you to the Winter Lady and then to the Summer Lady. Good enough?"

I frowned at the tiny faerie. "Does she understand me?"

I barely saw Elidee stamp a tiny foot. The scarlet light around her flickered sharply, twice.

"Yes," Toot-toot translated. "Two lights for yes, and one light for no."

"Two for yes, one for no," I muttered.

Toot frowned. "Or is that one for yes and two for no? I can never keep it straight." And with that, the little faerie blurred and zipped past me and away to join the swarm of softly flashing lights demolishing the pizza.

Elidee, for her part, recovered from the miniature cyclone that Toot-toot left in his wake, whirled around dizzily for a few moments, then spiraled down to me and settled on the bridge of my nose. My eyes crossed trying to look at her. "Hey," I said, "do I look like a couch to you?"

Two flashes.

I sighed. "Okay, Elidee. Do you want any pizza before we go?"

Two flashes again, brighter. The tiny faerie leapt up into the air again and zoomed over to the cloud around the pizza.

Footsteps came down the alley, then Billy stepped out of the shadows, pulling his sweatshirt down over his muscular stomach. I felt a brief and irrational surge of jealousy. I don't have a muscular stomach. I'm not overlapping my belt or anything, but I don't have abs of steel. I don't even have abs of bronze. Maybe abs of plastic.

Billy blinked at the pizza for a moment and said, "Wow. That's sort of pretty. In a Jaws kind of way."

"Yeah," I said. "Don't look at it for too long. Faerie lights can be disorienting to mortals."

"Gotcha," Billy said. He glanced back at me. "How'd it go? You get what you needed?"

"Yeah," I said. "You?"

He shrugged. "Alley isn't the best place to pick up scents, but I should be able to recognize them again if I'm in my other suit. They didn't smell quite normal."

"Gee, what are the odds."

Billy's teeth showed in the dark. "Heh. So what are we waiting for?"

Elidee picked just then to glide back over to me and settle once more on the bridge of my nose. Billy blinked at her and said, "What the hell?"

"This is our guide," I said. "Elidee, this is Billy."

Elidee flashed twice.

Billy blinked again. "Uh, charmed." He shook his head. "So? What's the plan?"

"We go confront the Winter Lady in her underground lair. I do the talking. You stay alert and watch my back."

He nodded. "Okay. You got it."

I looked over to see the last piece of pizza lifted up into the air by greedy faerie hands. They clustered around it, tearing and ripping, and it was gone in seconds. With that, the faeries swarmed away like a squadron of potbellied comets and vanished from view.

Elidee fluttered off my nose and started drifting down the alley in the other direction. I followed her.

"Harry?" Billy asked, his voice a touch hopeful. "Are you expecting trouble?"

I sighed and rubbed at the space between my eyebrows.

Definitely getting a headache. It was going to be a long night.
