One of the EMTs offered me a bottle of water, and I rinsed the worst of the blood from my hands.

Ethan walked toward me, looked me over, and I did the same to him. Limbs still connected. Filthy and blood smeared, like me, but generally healthy.

“I’m okay,” I said, anticipating the question. “You?”

He nodded, looked down at his now-untucked shirt and ripped pants. “The streets of Chicago are filthy. I don’t recommend rolling around on them.”

I looked down. I’d lost a sleeve, the lace along the bottom of my dress had been shredded, and blood stained the front in ugly vermillion streaks.

“Yeah, my dress is toast.”

He glanced down at it. “You and clothing. At least the wedding was already over.”

I blanched as I realized what would come. I’d have to take the dress back to the House, where Helen would undoubtedly see it. I could all but feel the lecture taking shape, judgment forming like a cloud over us, never mind that I’d paid for the damn thing.

“Helen,” I said, looking up at him, and watched understanding dawn in his eyes.

His gaze went steely. “We’ll move. Our bags are already at the hotel. We’ll just pick up and leave, and she’ll never know what became of it.”

Until the dozens of passersby with cell phones and reporters with cameras—all of whom were outside the hastily hung caution tape—shared their images with the world.

“Too late for that,” I said, and looked back at the carnage that we’d helped wreak tonight.

There had been more humans than supernaturals, but we had more strength and more firepower, literally and figuratively. Some had been knocked out, some were still squirming, and some were tied to bike racks with more abandoned bow ties. More than a dozen prone humans on the ground while we stood, bloodied and torn, over them—humans who’d come down with some kind of delusional disorder we’d seen in a vampire in Cadogan House.

“It wasn’t just Winston,” I said.

“No,” Ethan said. “It wasn’t just Winston. And we need to know why, and how.”

In addition to the people on the ground, two trash receptacles were on fire, sending the scents of burning plastic and garbage into the air. Blood spattered and pooled on the concrete, reflecting the cruisers’ blue and red lights.

When four uniformed CPD officers emerged from their cruisers, we lifted our hands instinctively. But for the wedding attire, it would have looked like we’d made a breakfast buffet of the neighborhood.

My grandfather and Jeff hustled toward us from the library, both still in their pristine suits.

My grandfather pulled out his identification. “I’m the Ombudsman,” he said. “The perpetrators are all on the ground. These are the ones who kept them from killing each other.”

We gave the cops a minute to orient themselves, holster their weapons, and for the officer in charge to find my grandfather.

“Oh, Merit,” Mallory said, joining us. “Your dress.”

“I know. Yours isn’t much better.” There were small circular burns and ugly red smears across the pale green lace.

She glanced down. “Oh yeah. Got a little singed with that last bombardment. Guess I won’t be turning this into a cocktail dress.”

“And I guess I won’t be getting married again.” Not that I’d want a repeat of this evening. Or the latter part of it, anyway.

Accompanied by my grandfather, a detective walked toward us, badge hanging from a chain around his neck. He had a pale, lived-in face, a crop of white hair, and a suit that was turned out, from the sharp lapels to pixel-thin stripes to pocket square. I wouldn’t have been surprised to see spats beneath the pants’ cuffs.

“One dead, twelve injured to some degree,” my grandfather reported. Ambulances were still rushing to and away from the scene, carrying the humans who’d been part of the mob to nearby hospitals.

“I’m Detective Pulaski,” said the detective, notepad in hand. “Who wants to start?”

“We stumbled into it,” Ethan said. “We were taking wedding photographs, rounded the corner, and there they were. Fighting and talking about delusions.”

My grandfather’s gaze widened, and he looked at me. I nodded at the unspoken question. “Same as Winston. They’re panicked and afraid, and they hear screaming. And because of that, for whatever reason, they become violent.”

“Winston Stiles,” my grandfather explained to Pulaski. “A vampire who attacked Merit last night in Cadogan House. He’s currently in lockup at the supernatural facility.”

Pulaski looked back. “Any of these people vampires?”

“All humans,” Ethan said.

“So a vampire went crazy, and then a bunch of humans went crazy?”

Was it contagious? he meant. Were the delusions spreading across the city?

“Vampires did not infect humans,” Ethan said. But there was worry in his eyes. We didn’t know how this had spread—whatever it was. And the only other person we’d seen with delusions had been a vampire in our House.

“Then how did it spread?”

“Maybe it didn’t,” Mallory said, and we all looked at her.

“Delusions aren’t generally contagious, and they don’t have any other symptoms.”

“So what’s the other option?” Pulaski asked.

“They’re telling the truth,” Mallory said. She pushed back the hair that brushed her face, her pale manicure—the same we’d all gotten for the wedding—chipped at the edges. “They’re having the same delusions because they’re hearing the same things. They’re hearing something real.”

Ethan tilted his head. “If the sound—or its origin—is real, why can’t we hear it? Why isn’t everyone affected?”

“I don’t know,” Mallory said. “I think that’s what we have to figure out. And that doesn’t even get to the bigger question.”

“Which is?” Ethan prompted.

She looked at him. “Who is screaming? Who wants so badly to be heard?” She spread her gaze across the city like she was looking for an enemy sail.

“Sorcha?” Ethan asked.

Mallory shook her head. “The wards are intact.”

“And there’s no way for her to get around that?” Ethan asked. “To circumvent it?”

We’d covered this ground before, of course. When the wards were proposed, we’d gone over every detail of the magic, of the wards, of the degree to which they’d give us protection—and fair warning.

“The wards are a circuit. She uses magic, it breaks the circuit, and we hear about it. We haven’t heard about it; ergo . . .”

“It’s not Sorcha,” Ethan concluded.

Mallory nodded. “Besides, she’s an alchemical witch. This doesn’t feel like alchemy.”

Pulaski held up his hand. “I’m not interested in the magical mumbo jumbo. I’ll leave that to you. What I want to know is what, exactly, happened here. In detail.”

“I’ll walk you through it,” Catcher said, and led him a few feet away, pointing at the spot where we’d rounded the corner some unfathomably long time ago.

My grandfather followed them but looked back at us, circled a finger in the air. He wanted us to keep going, to keep talking it through.

“So it’s someone else’s magic?” Ethan asked.

“It has to be,” Mallory said. “I just don’t know whose, or at least not yet. Although there is that weird metallic thing.”

“Yeah,” I said, turning back to Mallory. “I sensed the same thing after seeing Winston. I thought it was because of the delusions. Like, he’d been sick, which gave his magic a weird scent. But maybe it’s a signature of some kind. Is it associated with a certain kind of magic or creature?”

She shook her head. “Not that I’m aware of, but I’ll have to check the books.”

“Paige is out of town,” Ethan said, “or I’d have her look, too.” Paige was a sorceress who practically lived in Cadogan House, mostly owing to her relationship with our Librarian. “The Librarian’s at an ALA conference in New York,” Ethan added. “She’s with him.”
