“Simon.” She thought of his mother, turning him away from her door. You shouldn’t do that. Not to your child. “How long have you known? About Robert and Maryse?”

“Months.” He moved toward the front gate of the house. “I always wanted to help her, but she never wanted me to say anything, do anything—your mother knows, by the way. She told Izzy who Robert had the affair with. It wasn’t anyone she’d ever heard of. I don’t know if that makes it worse or better.”

“What? Simon, you’re wobbling. Simon—”

Simon crashed into the fence around the Inquisitor’s house with a loud rattling noise. “Isabelle!” he called, tipping his head back. “Isabelle!”

“Holy—” Clary grabbed Simon by the sleeve. “Simon,” she hissed. “You’re a vampire, in the middle of Idris. Maybe you shouldn’t be shouting for attention.”

Simon ignored this. “Isabelle!” he called again. “Let down your raven hair!”

“Oh, my God,” Clary muttered. “There was something in that blood Raphael gave you, wasn’t there? I’m going to kill him.”

“He’s already dead,” Simon observed.

“He’s undead. Obviously he can still die, you know, again. I’ll re-kill him. Simon, come on. Let’s head back, and you can lie down and put ice on your head—”

“Isabelle!” Simon shouted.

One of the upper windows of the house swung open, and Isabelle leaned out. Her raven hair was unbound, tumbling around her face. She looked furious, though. “Simon, shut up!” she hissed.

“I won’t!” Simon announced mutinously. “For you are my lady fair, and I shall win your favor.”

Isabelle dropped her head into her hands. “Is he drunk?” she called down to Clary.

“I don’t know.” Clary was torn between loyalty to Simon and an urgent need to get him out of there. “I think he may have gotten some expired blood or something.”

“I love you, Isabelle Lightwood!” Simon called, startling everyone. Lights were going on all through the house, and in neighboring houses as well. There was a noise from down the street, and a moment later Aline and Helen appeared; both looked frazzled, Helen in the middle of tying her curly blond hair back. “I love you, and I won’t go away until you tell me you love me too!”

“Tell him you love him,” Helen called up. “He’s scaring the whole street.” She waved at Clary. “Good to see you.”

“You, too,” Clary said. “I’m so sorry about what happened in Los Angeles, and if there’s anything I can do to help—”

Something came fluttering down from the sky. Two things: a pair of leather pants, and a puffy white poet shirt. They landed at Simon’s feet.

“Take your clothes and go!” Isabelle shouted.

Above her another window opened, and Alec leaned out. “What’s going on?” His gaze landed on Clary and the others, his eyebrows drawing together in confusion. “What is this? Early caroling?”

“I don’t carol,” said Simon. “I’m Jewish. I only know the dreidel song.”

“Is he all right?” Aline asked Clary, sounding worried. “Do vampires go crazy?”

“He’s not crazy,” said Helen. “He’s drunk. He must have consumed the blood of someone who’d been drinking alcohol. It can give vampires a sort of—contact high.”

“I hate Raphael,” Clary muttered.

“Isabelle!” Simon called. “Stop throwing clothes at me! Just because you’re a Shadowhunter and I’m a vampire doesn’t mean we can never happen. Our love is forbidden like the love of a shark and a—and a shark hunter. But that’s what makes it special.”

“Oh?” Isabelle snapped. “Which one of us is the shark, Simon? Which one of us is the shark?”

The front door burst open. It was Robert Lightwood, and he did not look pleased. He stalked down the front walk of the house, kicked the gate open, and strode up to Simon. “What’s going on here?” he demanded. His eyes flicked to Clary. “Why are you shouting outside my house?”

“He’s not feeling well,” Clary said, catching at Simon’s wrist. “We’re going.”

“No,” Simon said. “No, I—I need to talk to him. To the Inquisitor.”

Robert reached into his jacket and drew out a crucifix. Clary stared as he held it up between himself and Simon. “I speak to the Night’s Children Council representative, or to the head of the New York clan,” he said. “Not to any vampire who comes to knock at my door, even if he is a friend of my children. Nor should you be in Alicante without permission—”

Simon reached out and plucked the cross out of Robert’s hand. “Wrong religion,” he said.

Helen made a whistling noise under her breath.

“And I was sent by the representative of the Night’s Children to the Council. Raphael Santiago brought me here to speak to you—”

“Simon!” Isabelle hurried out of the house, racing to place herself between Simon and her father. “What are you doing?”

She glared at Clary, who grabbed Simon’s wrist again. “We really need to go,” Clary muttered.

Robert’s gaze went from Simon to Isabelle. His expression changed. “Is there something going on between you two? Is that what all the yelling was about?”

Clary looked at Isabelle in surprise. She thought of Simon, comforting Isabelle when Max died. How close Simon and Izzy had become in the past months. And her father had no idea.

“He’s a friend. He’s friends with all of us,” Isabelle said, crossing her arms over her chest. Clary couldn’t tell if she was more annoyed with her father or with Simon. “And I’ll vouch for him, if that means he can stay in Alicante.” She glared at Simon. “But he’s going back to Clary’s now. Aren’t you, Simon?”

“My head feels round,” Simon said sadly. “So round.”

Robert lowered his arm. “What?”

“He drank some drugged blood,” said Clary. “It isn’t his fault.”

Robert turned his dark blue gaze on Simon. “I’ll talk to you tomorrow at the Council meeting, if you’ve sobered up,” he said. “If Raphael Santiago has something he wants you to speak to me about, you can say it in front of the Clave.”

“I don’t—” Simon began.

But Clary cut him off with a hasty: “Fine. I’ll bring him with me to the Council meeting tomorrow. Simon, we have to get back before dark; you know that.”

Simon looked mildly dazed. “We do?”

“Tomorrow, at the Council,” Robert said shortly, turned, and stalked back into his house. Isabelle hesitated a moment—she was in a loose dark shirt and jeans, her pale feet bare on the narrow stone path. She was shivering.

“Where did he get spiked blood?” she asked, indicating Simon with a wave of her hand.

“Raphael,” Clary explained.

Isabelle rolled her eyes. “He’ll be all right tomorrow,” she said. “Put him to bed.” She waved to Helen and Aline, who were leaning on the gateposts with unabashed curiosity. “See you at the meeting,” she said.
