He thought, How beautiful.

Kit blinked. Though the other boy wasn’t looking directly at him, he seemed to note the movement. In a harsh whisper, he demanded, “Who are you? What are you doing here? You’re too young to be Johnny Rook.”

His voice was lovely. Clear and low, with a rasp to it that made him sound older than he was. A rich boy’s voice.

“No,” said Kit. He felt dazed and puzzled, as if a bright camera flash had gone off in his eyes. “I’m not.”

The boy still wasn’t looking directly at Kit. As if Kit weren’t worth looking at. Kit’s dazed feeling was starting to fade, to be replaced by anger.

“Go on,” Kit said, challenging. “Figure it out.”

The boy’s expression clouded, then cleared. “You’re his son,” he said. “Johnny Rook’s son.”

And then his lip did curl, just the slightest curl of contempt, and anger boiled up in Kit. He jerked aside fast, away from the dagger, and kicked out. The other boy spun, but Kit caught him with a glancing blow. He heard a cry of pain. The light tumbled from the boy’s hand, winking out, and then Kit was being shoved up against the wall again, a hand scrabbling to fist itself in his shirt, and the dagger was back at his throat, and the other boy was whispering, “Be quiet, be quiet, be quiet,” and then the room was full of light.

The other boy froze. Kit looked up to see two other Shadowhunters standing on the cellar steps: a boy with blazing blue-green eyes and the blond girl he had seen at the Shadow Market the week before. They were both staring—not at him, but at the boy gripping his shirt.

The boy winced but held his ground, defiance chasing alarm across his face. Aha, Kit thought with dawning realization. You’re not supposed to be down here, are you?

“Tiberius Blackthorn,” said the boy with blue-green eyes. “What on earth are you doing?”

Emma stood and gawked at Ty, completely brought up short. It was as if the Institute had suddenly appeared in the middle of Johnny Rook’s cellar: The sight of Ty was familiar, and yet totally incongruous.

Ty looked rumpled and more frazzled than she’d seen him in years, though his grip on his dagger was steady. Diana would have been pleased. She would probably not have been pleased that he was pointing it at the throat of a mundane boy—he looked about fifteen, and oddly familiar. She’d seen him before, Emma realized, at the Shadow Market. His hair was a mass of blond tangles; his shirt was clean but ragged, his jeans worn to a faded pallor. And he looked ready to punch Ty in the face, which was unusual for a mundane in his position. Most of them were much more unsettled by a knife to the throat.

“Ty,” Julian said again. He looked furious—fury with an edge of panic. “Ty, let go of Johnny Rook’s son.”

The blond boy’s eyes widened. “How did you—how do you know who I am?” he demanded.

Julian shrugged. “Who else would you be?” He tilted his head to the side. “Maybe you know something about the Lottery at the Midnight Theater?”

“Jules,” Emma said. “He’s just a kid.”

“I’m not a kid!” the boy protested. “And my name is Kit.”

“We’re trying to help,” Julian said. The blond boy—Kit—scowled. Julian softened his voice. “We’re trying to save lives.”

“My father told me that’s what Shadowhunters always say.”

“Do you believe everything he says?”

“He was right this time, wasn’t he?” Kit pointed out. His gaze slid to Emma; she remembered noticing that he had the Sight. She’d thought he was Rook’s assistant, though, not his son. They looked nothing alike. “You said it.”

“I meant—” Julian began.

“I don’t know anything about a lottery,” Kit snapped. He glanced at Tiberius. What was odder, perhaps, was that Ty was looking at him. Emma remembered Ty, years ago, saying, Why do people say “look at me” when they mean “look at my eyes”? You could be looking at any part of a person and you’re still looking at them. But he was looking curiously at Kit’s eyes as if they reminded him of something.

“Kit!” The voice was a roar. Emma heard skidding footsteps on the stairs, and Johnny Rook appeared. One of his sleeves was singed. Emma had never seen him look so furious. “Leave my son alone!”

Ty steadied his grip on the knife, straightening his spine. He faced Johnny Rook without a speck of fear. “Tell us about the Lottery,” he said.

Kit winced. Emma could see it, even in the gloom. Ty didn’t seem frightening to her, but then, she’d cuddled him when he was three years old. But fear was clear in Johnny Rook’s face: As far as he was concerned, Nephilim had snuck a Shadowhunter into his basement to murder his son.

“I’ll give you Casper Sterling’s address,” he said as Kit stared at him, looking bewildered. Clearly he had rarely seen his father so shaken. “I’ve got it, okay? He’s got a bunch of identities, he isn’t easy to find, but I know where he lives. All right? Good enough? Let my son go!”

Ty lowered the knife and stepped back. He kept it in his hand, his eyes on Kit as the other boy rubbed ruefully at the dent in his throat. “Dad, I—” Kit started.

“Be quiet, Kit,” Johnny Rook snapped. “I’ve told you. Don’t say anything in front of Nephilim.”

“We’re on the same side,” Julian said in his calmest voice.

Johnny Rook whirled on him. His face was red, his throat working. “Don’t you dare tell me what side I’m on, you know nothing, nothing—”

“Enough!” Emma shouted. “By the Angel, what are you so frightened of?”

Johnny slammed his mouth shut. “I’m not frightened,” he said through his teeth. “Just get out,” he said. “Get out, and don’t ever come here again. I’ll text you the address but after that, don’t call, don’t ask me for favors. We’re done, Nephilim.”

“Fine,” Emma said, gesturing for Ty to come toward her and Julian. “We’ll go. Ty—”

Ty slid the knife he’d been holding into his belt and darted up the steps. Julian turned and went after him. The boy at the bottom of the stairs didn’t watch them go; his eyes were fixed on his father.

He wasn’t much younger than Emma—maybe by a year or two—but she felt a sudden inexplicable surge of protectiveness toward Johnny Rook’s son. If he had the Sight, then all of Downworld was open to him: terrifying and inexplicable. In his own way he was like Tiberius, living in a world he saw differently than everyone else.

“Fine, Johnny,” Emma said again, loudly. “But if you change your mind, you have my number in your phone. Under Carstairs.”

Johnny Rook glared at her.

“Call me,” Emma said again, and this time she looked directly at Kit. “If you ever need anything.”

“Get OUT.” Rook looked as if he were going to explode or have a heart attack, so with a last look over her shoulder, Emma went.

Emma found Ty out by the car. Clouds had gathered, scudding in quick bursts across the sky. Ty was leaning against the trunk, the wind ruffling his black hair. “Where’s Jules?” she asked as she got close.
