Emma thought of the one Silent Brother she’d ever liked. She missed him still, sometimes.

The alley suddenly lit up like daylight. Blinking, Emma turned to see that a familiar pickup truck had pulled into the alley’s entrance. It came to a stop, headlights still on, and Diana Wrayburn jumped down from the driver’s seat.

When Diana had come to work as the tutor to the children of the Los Angeles Institute five years ago, Emma had thought she was the most beautiful woman she’d ever seen. She was tall and spare and elegant, with the silvery tattoo of a koi fish standing out across the dark skin of one arched cheekbone. Her eyes were brown with flecks of green in them, and right now they were flashing with angry fire. She was wearing an ankle-length black dress that fell around her long body in elegant folds. She looked like the dangerous Roman goddess of the hunt she was named for.

“Emma! Cristina!” She hurried toward them. “What happened?

Are you all right?”

For a moment Emma paused the glaring and let herself enjoy being hugged fiercely. Diana had always been too young for Emma to think of her as a mother, but an older sister, maybe. Someone protective. Diana let go of her and hugged Cristina too, who looked startled. Emma had long had the suspicion that there hadn’t been much hugging in Cristina’s home. “What happened? Why are you trying to burn a hole through Brother Enoch with your eyeballs?”

“We were patrolling—” Emma began.

“We saw a fey stealing from humans,” Cristina added quickly.

“Yes, and I stopped him and told him to turn out his pockets—”

“A faerie?” A look of disquiet came over Diana’s face. “Emma, you know you shouldn’t confront one of the Fair Folk, even when Cristina’s with you—”

“I’ve fought Fair Folk before,” Emma said. It was true. Both she and Diana had fought in the Shadowhunter city of Alicante when Sebastian’s forces had attacked. The streets had been full of faerie warriors. The adults had taken the children and walled them up in the fortresslike Hall of Accords, where they were meant to be safe. But the faeries had broken the locks. . . .

Diana had been there, laying to the right and left of her with her deadly sword, saving dozens of children. Emma had been one of those saved. She had loved Diana since then.

“I had a feeling,” Emma went on, “that something bigger and worse was happening. I followed the faerie when he ran. I know I shouldn’t have, but—I found that body. And it’s covered in the same marks my parents’ bodies were. The same markings, Diana.”

Diana turned to Cristina. “Could you give us a moment alone, please, Tina?”

Cristina hesitated. But as a guest of the Los Angeles Institute, a young Shadowhunter on Leave, she was required to do as the senior staff of the Institute requested. With a glance at Emma, she moved away, toward the spot where the body still lay. It was surrounded by a ring of Silent Brothers, like a flock of pale birds in their parchment robes. They were sprinkling a sort of shimmering powder over the markings, or at least that’s how it looked. Emma wished she were closer and could see properly.

Diana exhaled. “Emma, are you sure?”

Emma bit back an angry retort. She understood why Diana was asking. Over the years there had been so many false leads—so many times Emma had thought she had found a clue or a translation for the markings or a story in a mundane newspaper—and every time she had been wrong.

“I just don’t want you to get your hopes up,” Diana said.

“I know,” Emma said. “But I shouldn’t ignore it. I can’t ignore it. You believe me. You’ve always believed me, right?”

“That Sebastian Morgenstern didn’t kill your parents? Oh, honey, you know I do.” Diana patted Emma’s shoulder lightly. “I just don’t want you to get hurt, and with Julian not here . . .”

Emma waited for her to go on.

“Well, with Julian not here, you get hurt more easily. Parabatai buffer each other. I know you’re strong, you are, but this is something that cut you so deeply when you were just a child. It’s twelve-year-old Emma that reacts to anything to do with your parents, not almost-adult Emma.” Diana winced and touched the side of her head. “Brother Enoch is calling me over,” she said. Silent Brothers were able to communicate with Shadowhunters using telepathy only they could hear, though they were also able to project to groups if the need arose. “Can you make it back to the Institute?”

“I can, but if I could just see the body again—”

“The Silent Brothers say no,” Diana said firmly. “I’ll find out what I can, and I’ll share it with you? Deal?”

Emma nodded reluctantly. “Deal.”

Diana headed off toward the Silent Brothers, stopping to talk briefly to Cristina. By the time Emma reached the car she had parked, Cristina had joined her, and they both climbed in silently.

Emma sat where she was for a moment, drained, the car keys dangling from her hand. In the rearview mirror she could see the alleyway behind them, lit up like a baseball stadium by the truck’s powerful headlights. Diana was moving among the parchment-robed Silent Brothers. The powder on the ground was white in the glare.

“Are you all right?” Cristina said.

Emma turned to her. “You have to tell me what you saw,” she begged. “You were close to the body. Did you hear Diana say anything to the Brothers? Are they definitely the same markings?”

“I don’t need to tell you,” Cristina said.

“I—” Emma broke off. She felt wretched. She’d messed up the whole plan for the night, lost their faerie criminal, lost her chance of examining the body, probably hurt Cristina’s feelings. “I know you don’t. I’m really sorry, Cristina. I didn’t mean to get you in trouble. It’s just that—”

“I didn’t say that.” Cristina fumbled in the pocket of her gear. “I said I didn’t need to tell you, because I meant I could show you. Here. Look at these.” She held out her phone, and Emma’s heart leaped—Cristina was scrolling through picture after picture she’d taken of the body and the Brothers, the alley, the blood. Everything.

“Cristina, I love you,” Emma said. “I will marry you. Marry you.”

Cristina giggled. “My mother’s already picked out who I’m going to marry, remember? Imagine what she’d say if I brought you home.”

“You don’t think she’d like me more than Perfect Diego?”

“I think you would be able to hear her screaming in Idris.”

Idris was the home country of the Shadowhunters, where they had first been created, where the Clave held its seat. It was tucked away at the intersection of France, Germany, and Switzerland, hidden by spells from mundane eyes. The Dark War had ravaged its capital city of Alicante, which was still being rebuilt.

Emma laughed. Relief was coursing through her. They had something after all. A clue, as Tiberius would say, head stuck in a detective novel.

Missing Ty suddenly, she reached to start up the car.

“Did you really tell that faerie that you broke up with Cameron and not the other way around?” Cristina said.

“Please don’t bring that up,” Emma said. “I’m not proud of it.”
