The bank was down a very short block. As if we'd agreed on it, Aubrey and I dropped the subjects of parasites and spirits when we entered the dry, cool desert of the financial world. The lawyer had given me the name of the woman to ask for when I got to the desk. I expected to be put in one of the little wood-grain cubicle offices that competed for s.p.a.ce with the line of tellers, but instead Aubrey and I were escorted to an elevator, and then up to a plush private office where I presented my paperwork, signed theirs, and was given access to the first of Eric's cash accounts. They promised me an ATM card in about a week. Just to see if I could, I withdrew ten thousand dollars in cash. The woman didn't blink.

"Dinner's on me," I said as we walked back out onto the street. Aubrey looked stunned.

"It really is," he said.

There were other banks and more paperwork, but I put them aside. My hands kept finding their way to the keys for the storage units, fidgeting with them. Whatever I was getting into, I now had enough money in my name to do whatever needed doing. Aubrey was oddly quiet as we walked, and I took the chance to pull out the MapQuest printouts and see which of my next stops looked closest. I didn't realize how much the August heat had been pressing on me until Aubrey started up the car and the first blast of the air conditioner hit my skin.

"Okay," I said. "This one's on Eighteenth Street. That should be pretty close, right?"

"What? Oh. Yeah, that's over by the Children's Hospital. We could almost walk to that."

"Let's drive anyway," I said. And then, "Hey, are you all right?"

"I'm fine," Aubrey said. "I just...Eric and I never talked about money. I didn't know that he was in that kind of tax bracket."

"Me either," I said as we pulled out into traffic. "Turns out there was a whole lot I didn't know."

Aubrey smiled, but his brows didn't quite lose their furrow. It was only a few minutes before we pulled into the storage facility. The gate code was written on the key chain. I read it to Aubrey, and he leaned out and punched the b.u.t.tons. The bar rose, and we headed into the asphalt rat maze that was the storage joint.

I didn't know quite what I'd expected, but this place wasn't it. It was too prosaic. White stucco buildings with green garage doors lined a dozen tight alleyways. A family was loading boxes into the back of a big orange U-Haul truck, a girl maybe eight years old waving to us as we pa.s.sed.

Aubrey cruised down two alleys, struggling to make the turns before I saw the numbers for Eric's unit. We came to a halt just outside it. I fit the key into the padlock. The click as it came free was soft and deep. The lock was heavier in my hand than I'd expected. I took hold of the rolling door, prepared to lift it up, but I hesitated. Despite the heat, I shivered.

"The people who have the thing," I said. "They don't know it, do they?"

"The people who have what?"

"The T. whatever. The parasite," I said.

"No. I mean, you could test for antibodies and find out, but generally there aren't many symptoms."

"Except that it changes who they are," I said.

Aubrey wiped the sweat off his forehead with the back of one hand. A few alleys over, the U-Haul truck started up with a loud rattle. I kept my fingertips on the shaped metal handle of the garage door, hesitating.

"Is something wrong?" he asked.

Yes, I wanted to say. I fought four people with guns to a standstill yesterday. I walked through Midian's magic alarms like they weren't there. I have more money in my backpack right now than I've ever had in my bank account. And what if whatever's in here changes things again? I didn't particularly like who I was last week, but at least I knew who I was.

"No," I said. "It's nothing."

"You're cool?"

"Cuc.u.mberesque," I said.

I tightened my grip on the handle and pulled. The garage door shrieked in metallic complaint and rose up. Daylight spilled into a concrete cube behind it, smaller than an actual garage. White cardboard boxes were stacked three deep against the walls, and an industrial-looking set of steel shelves at the back supported a collection of odd objects. A violin case, a duffel bag, two translucent bowling b.a.l.l.s, a stuffed bear with a wide pink heart embroidered on its chest.

It looked like a secondhand store, but it felt like a puzzle. I picked up the stuffed bear. The nap of the fake fur was worn, the thread that made its mouth was loose and thin with use. A child had loved this bear once. I wondered who that had been, and what had brought the beloved object here.

"I've got something," Aubrey said.

He was standing beside the stack of boxes, the top one open. Looking over his shoulder, I saw a stack of three-ring binders with words stenciled on the spines: INVISIBLE COLLEGE-19701976. INVISIBLE COLLEGE-19771981. There were easily a dozen of them. Aubrey lifted one out and opened it.

"What is it?"

"Newspaper clippings. Lists of names and places," he said with a sigh. "I don't know what it all means."

"Let's get it in the car," I said. I suddenly wanted very badly to just leave. "Let's get as much of this out of here as we can and we'll make sense of it later."

He grunted in agreement and hauled the box out toward his car. I grabbed the next box and followed him. It wasn't until we picked the duffel bag up off the shelf that we found the guns.

Six.

This is nice," Midian said, chambering a round with the rolling sound that only shotguns make. He looked down the barrel and nodded his appreciation. "Good workmanship."

Chogyi Jake and Aubrey were squatting by the coffee table. Three empty sh.e.l.ls lay on the table's edge, two small piles of debris in the center. Ex stood by the kitchen table, copying the diagrams from the Inca Street whiteboard onto a legal pad.

"They're all loaded the same way," Aubrey said. "Silver shot, rock salt, and I'm not sure what this is."

"Iron filings," Ex said. "According to this, he loaded them with silver, salt, and iron."

"If he wasn't sure precisely what form the rider took, that would cover a very broad range," Chogyi Jake said.

"Or if he was loading for more than one," Midian said. "You gotta remember, he was hiring on a loupine for muscle. They're tough b.a.s.t.a.r.ds, but not the last word in reliable."

I sat on the couch, my knees drawn up to my chest, watching and listening. Through the evening, the four men had decoded Eric's plan, details unfolding like petals falling open.

According to the calendar Eric had left us, the Invisible College was scheduled to begin the rituals that would summon riders and inject them into the new crop of initiates within the next day or two. As the ceremonies continued, the gap between the real world and what Eric called the Pleroma and Aubrey referred to as Next Door would turn permeable. Randolph Coin would be at his most vulnerable just before the final ceremony, scheduled for just after dawn on August 11, one week from today.

So now we had a countdown. Seven days.

In seven days, we were going to kill someone. The thought made my skin crawl. Or we were going to get the rat b.a.s.t.a.r.d who'd killed Eric, which felt better. My head kept bouncing between anxiety and wrath, like I was two different people.

"This is all from the one storage unit, right?" Ex asked, walking into the main room. "You didn't make it to the other one?"

"No room in the car," Aubrey said.

"We need to get to that other one," Ex said. "I think it has props for the invocation to draw Coin out. We'll need to inventory those."

"I've got to..." I said, standing and heading for the back door. "Excuse me."

I heard the silence behind me as I walked out into the backyard. I could feel their eyes on my back even after I closed the door. The yard was immaculate: the gra.s.s green as emeralds and freshly cut, mums in the flower beds threatening to bloom, a cherry tree with a little overripe fruit still on the branches making the air heavy with sweetness and corruption. I sat in the darkness and stared up at the moon. I saw the inked face of the blue-eyed woman.

The door slid open behind me, and then just as quietly shut.

"Hey. Are you all right?"

Aubrey looked uncertain in the dim light. He was wearing blue jeans and a T-shirt with the logo of an old science fiction show, long since off the air. His hair was mussed. It occurred to me that we'd forgotten to stop by his labs at the university.

"I can't do this," I said. "We're talking about murdering someone."

He came to my side and lowered himself to the ground, legs crossed.

"I thought you understood," he said. "These aren't people. Not anymore. They're-"

"Riders," I said. "Spiritual parasites that have magic powers and take over people's bodies. I understand that. I just..."

I closed my eyes and saw Midian fire his Lugar into the back of the woman's head.

"Jayne?"

"I just don't believe it," I said. "I want to. But I don't."

"You think we're lying?" he asked. The idea seemed to surprise him. I didn't laugh, partly because it wasn't funny.

"It isn't about trust. I believe that you think it's true," I said. "That's not the same. I grew up with a father who knew how the world worked. Who knew how G.o.d worked, and what was right and what was wrong. And I believed everything he said because he was sure. And then when it turned out that I wasn't sure..."

I spread my hands.

"Knowing that you all believe it isn't the same as believing it myself," I said. "And I can't do this if it isn't true. I can go to the police. I can hire a bodyguard. I can do a lot of different things, but I can't kill someone."

Aubrey was quiet. I wanted to brush the hair away from his eyes. I wanted to ask him to forgive me.

"If you knew that riders were real," he said. "If you had evidence that the world really does work the way we all say it does, could you trust me about Coin and the Invisible College?"

"I don't know," I said. "Probably."

He was silent for a moment, then sighed and looked up at the moon with me. I could feel the subtle warmth of his body. Somewhere nearby, a police siren rose and faded away. My stomach felt like I swallowed a bowlful of lead shot.

"You're angry?" I asked.

"What? No! No, I'm not mad. I'm just thinking."

"Did you believe it? When Eric came to you and told you all about this...this stuff. Did you believe it?"

"No," Aubrey said. "He had to prove it to me."

A minute later, he rose and walked slowly back into the house. I heard voices raised in conversation. Midian, Ex. I didn't think Chogyi Jake ever raised his voice, so if he was talking I might never know. He reminded me of my mother that way.

I had ten thousand dollars in my pocket, less forty that I'd spent on pizza and beer for the bunch of them. I could Google private investigators tonight, make a half-dozen calls in the morning, and set hounds on Randolph Coin's heels. If he was really the person who'd killed Eric, I could get the evidence and have the b.a.s.t.a.r.d thrown in jail for the rest of his life. I didn't know why that seemed to make less sense than magical vigilantes taking on a society of evil wizards.

I thought of the three small stones dropping at the apartment, one-two-three. It could have been some kind of magical alarm system. It could have been something else.

I put my head in my hands and hoped that my mind would clear. It didn't.

I heard Aubrey come back out. When I looked over, something was glowing white and blue in the palm of his hand. It said something about my state of mind that I thought it was a ball of witch fire or some other tiny miracle. Then he stepped a little closer, and it was just the screen of Eric's cell phone. He held it out to me.

"Call her," he said.

"Who?" I asked, taking the phone. It was warm.

"The woman that called. The one with the dog."

I looked down at the phone. The icon for voice mail was still there.

"What if she's with the Invisible College?" I said.

"I'll take one of the shotguns," Aubrey said, and something in his voice was light, even though I knew he was serious. I thumbed through the logs, found the most recent missed call, and selected the menu option that returned it. Aubrey sat next to me. The branches of the cherry tree shifted in the breeze.

"h.e.l.lo?" a woman said. I thought the voice was the same, but it seemed tighter.

"Hi," I said. "This is Jayne h.e.l.ler. I think you called my uncle Eric?"

"Oh, thank G.o.d," the woman said. She sounded like she was crying. "Oh, thank G.o.d."

I'D EXPECTED at the soonest, we'd arrange to meet the woman and her dog sometime in the morning. But ten minutes after I ended the call, Aubrey and I were in his minivan headed north for Boulder.

"It used to be left-wing hippie central, kind of the way Colorado Springs is the home port of all the right-wing nut jobs," Aubrey said. "There were a lot of people dabbling in alternative spiritualities and magic and drugs and things. These days, it's mostly people who feel like they're saving the planet because they're buying groceries from Whole Foods."

"Okay," I said.

"Did she tell you anything about what was going on?"

"Just that her dog wanted her to call us," I said. "I think it has to do with her boyfriend too, but I'm not sure."

"She was pretty upset, sounds like."

"Yeah," I said. Ahead of us, taillights tracked off into the darkness, lines of red in the black. "Yeah, she was pretty messed up. I don't know what we're doing, though. I don't know anything about what Eric used to do."

"I know enough to start," Aubrey said. "Hopefully it'll be simple."

We turned onto Highway 36, and then sooner than I'd expected, we were pulling onto the South Boulder Road exit. A knot was tying itself in my belly, embarra.s.sment and fear.

I was embarra.s.sed because I was about to go talk to a stranger-a desperate one-about supernatural ghosties slipping into her dog's mind, and only half of me thought it was possible. The fear was because the other half thought it was.

Candace Dorn's house was a pretty bungalow with a wide porch, complete with swing. A huge tree commanded the yard, choking out all compet.i.tion. Even the gra.s.s looked thin and unlikely where the tree's shadow would have fallen in daylight. All the lights were on, the windows blazing, like the woman was trying to push back night itself. Aubrey killed the engine, then reached into the backseat for the leather satchel he'd packed before we left. I grabbed my backpack.

One of the shotguns was back there too. He didn't take it out, and as we headed up the root-cracked concrete walk to the house, I wasn't sure if I was relieved at that or worried.

The woman who answered the door reminded me of my high school art teacher. She had dark, curly hair and skin that had tanned too many times, now permanently dark and leathery. She had a dieter's figure and a pianist's hands. Something in the way she held herself caught my attention, but I couldn't put my finger on it.

"Candace Dorn? I'm Jayne," I said. "This is Aubrey. He's here to help."
