Magnus edged toward the werewolves, to the woman who was the only one who remained human, even though her teeth and claws were growing apace.

“Why aren’t you fighting?” he demanded.

The werewolf woman glared at him as if he were impossibly stupid.

“Because Valentine’s here,” she snapped. “Because he has my daughter. He took her through there, and they said if we moved to follow her, they would kill her.”

Magnus did not have an instant to reflect on what Valentine might do to a helpless Downworlder child. He lifted a hand and blasted from his feet the stocky Shadowhunter at the single door at the far end of the room, and then Magnus ran toward the door.

He heard the cries behind him, of the Whitelaws demanding, “Bane, where are you—” and a shout, Magnus thought from Stephen, saying, “He’s going after Valentine! Kill him!”

Behind the door Magnus heard a low, awful sound. He pushed the door open.

On the other side of the door was a small ordinary room, the size of a bedroom, though there was no bed, only two people and a single chair. There was a tall man with a fall of white-blond hair, wearing Shadowhunter black. He was stooped over a girl who looked about twelve. She was fastened to the chair with silver cord, and was making a terrible low sound, a cross between a whine and a moan.

Her eyes were shining, Magnus thought for a moment, the moonlight turning them into mirrors.

His mistake lasted for the briefest of instants. Then Valentine moved slightly and the gleam of the girl’s eyes resolved in Magnus’s vision. The gleam was not her eyes. The moonlit shine was silver coins pressed to the girl’s eyes, tiny wisps of smoke escaping from beneath the bright discs as the tiny sounds escaped from between her lips. She was trying to suppress the sound of her pain, because she was so scared of what Valentine would do to her next.

“Where did your brother go?” demanded Valentine, and the girl’s sobbing continued, but she said nothing.

Magnus felt for a moment as if he had become a storm, black curling clouds, the slam of thunder and slash of lightning, and all the storm wanted was to leap at Valentine’s throat. Magnus’s magic lashed out almost of its own volition, leaped from both hands. It looked like lightning, burning so blue that it was almost white. It knocked Valentine off his feet and into a wall. Valentine hit the wall so hard that a crack rang out, and he slid to the floor.

That one act also used up far too much of Magnus’s power, but he could not think of that now. He ran over to the girl’s chair and wrenched the chain off her, then touched her face with painful gentleness.

She was crying now, more freely, shuddering and sobbing beneath his hands.

“Hush, hush. Your brother sent me. I’m a warlock; you’re safe,” he murmured, and clasped the back of her neck.

The coins were hurting her. They had to come off. But would removing them do more damage? Magnus could heal, but it had never been his specialty as it was Catarina’s, and he had not had to heal werewolves often. They were so resilient. He could only hope she would be resilient now.

He lifted the coins as gently as he could, and threw them against the wall.

It was too late. It had been too late before he’d ever entered the room. She was blind.

Her lips parted. She said, “Is my brother safe?”

“As safe as can be, sweetheart,” said Magnus. “I’ll take you to him.”

No sooner had he said the word “him” than he felt the cold blade sink into his back and his mouth fill with hot blood.

“Oh, will you?” asked Valentine’s voice in his ear.

The blade slid free, hurting as much on the way out as it had on the way in. Magnus gritted his teeth and gripped the back of the chair harder, kept himself arched over and protecting the child, and turned his head to face Valentine. The white-haired man looked older than the other leaders, but Magnus was not sure if he was actually older or if cold purpose simply made his face seem carved from marble. Magnus wanted to smash it.

Valentine’s hand moved, and Magnus only just managed to catch Valentine’s wrist before he found Valentine’s blade in his heart.

Magnus concentrated and made the clasp of his hand burn, blue electricity circling his fingers. He made the contact burn as the touch of silver had burned the girl, and he grinned as he heard Valentine’s hiss of pain.

Valentine did not ask his name as the others had, did not treat Magnus as that much of a person. Valentine simply stared at Magnus with cold eyes, the same way anyone might stare at a loathsome animal in their path and impeding their progress. “You are interfering in my business, warlock.”

Magnus spat blood into his face. “You are torturing a child in my city. Shadowhunter.”

Valentine used his free hand to deal Magnus a blow that sent Magnus staggering back. Valentine wheeled and followed him, and Magnus thought, Good. It meant that he was moving away from the girl.

She was blind, but she was a werewolf, smell and sound as important to her as sight. She could run, and find her way back to her family.

“I thought we were playing a game where we said what the other person was and what we were doing,” Magnus told him. “Did I get it wrong? Can I guess again? Are you breaking your own sacred Laws, asshole?”

He glanced at the girl, hoping she would run, but she seemed frozen to the spot with terror. Magnus did not dare call out to her in case it attracted Valentine’s attention.

Magnus lifted a hand, sketching a spell in the air, but Valentine saw the spell coming and dodged it. He leaped into the air and then bounded off the wall, Nephilim-swift, to lunge at Magnus. He scythed Magnus’s legs out from under him, and when Magnus landed, Valentine kicked him brutally hard. He drew a sword and brought it down. Magnus rolled so that it caught him a glancing blow along the ribs, cutting through shirt and skin but not hitting vital organs. Not this time.

Magnus dearly hoped he was not going to die here, in this cold warehouse, far from anyone he loved. He tried to rise from the floor, but it was slippery with his own blood, and the scraps of magic he had were not enough to heal or fight, let alone both.

Marian Whitelaw stood in front of him, her blades drawn and new runes shining on her arms. Her hair shone silver in his blurred vision.

Valentine swung his sword, and cut her almost in half.

Magnus gasped, salvation lost as quickly as it had been found, then turned his head toward the sound of more footsteps on the stone.

He was a fool to have hoped for another rescue. He saw one of Valentine’s Circle, standing in the doorway with his eyes fixed on the werewolf girl.

“Valentine!” Lucian Graymark shouted. He ran for the girl, and Magnus tensed, coiled himself for a leap, and then froze as he saw Lucian pick the girl up and wheel on his master. “How could you do this? She’s a child!”

“No, Lucian. She’s a monster in the shape of a child.”

Lucian was holding the girl, his hand in her hair, soothing and stroking. Magnus was starting to think he might have really misjudged Lucian Graymark. Valentine’s face was as white as bone. He resembled a statue more than ever.

Valentine said slowly, “Did you not promise me unconditional obedience? Tell me, what use have I for a second-in-command who undermines me like this?”

“Valentine, I love you and I share your grief,” said Lucian. “I know you are a good man. I know if you stop and think, you will see that this is madness.”

When Valentine took a step toward him, Lucian took a step back. He curved his hand protectively over the werewolf girl’s head as she clung to him with her small legs locked around his waist, and his other hand wavered as if he might go for his weapon.

“Very well,” Valentine said gently, at last. “Have it your way.”

He stood aside to let Lucian Graymark pass through the door and out into the corridor, and back into the room where the werewolves had thought they might be safe. He let Lucian bring the werewolves’ daughter back to them, and followed him at a distance.

Magnus did not trust Valentine for an instant. He would not believe the girl was safe until she was in her mother’s arms.

Lucian Graymark had bought Magnus enough time to gather up his magic. Magnus concentrated, felt his skin knit even as his power drained away.

He pulled himself up from the floor, and ran after them.

The fight in the room they had left was quieter, because there were so many dead. Someone had managed to turn the lights back on. There was a wolf lying dead on the ground, transforming inch by inch into a pale young man. Another young man lay dead beside him, one of the Circle, and in death they did not look so different.

Many of the Shadowhunters in Valentine’s Circle were still standing. None of the Whitelaws were. Maryse Lightwood had her face in her hands. Some of the others were visibly shaken. Now the shadows and the frenzy of battle had receded, and they were left in the light to look at what they had done.

“Valentine,” Maryse said, her voice imploring as her leader approached. “Valentine, what have we done? The Whitelaws are dead. . . . Valentine . . .”

They all looked to Valentine as he approached, clustered up to him like frightened children rather than adults. Valentine must have gotten hold of them very young, Magnus thought, but he found himself unable to care if they were brainwashed or deluded, not after what they had done. It seemed like there was no pity left in him.

“You have done nothing but try to uphold the Law,” said Valentine. “You know that all traitors to our kind must pay one day. If they had chosen to step aside, to trust us, their fellow children of the Angel, all would have been well.”

“What about the Clave?” said the curly-haired man, a note of challenge in his voice.

“Michael,” murmured Maryse’s husband.

“What of them, Wayland?” Valentine asked, his voice sharp. “The Whitelaws died because of rogue werewolves. It is the truth, and we will tell the Clave so.”

The only one of Valentine’s Circle not desperately listening was Lucian Graymark. He made his way to the werewolf woman, and placed the little girl into her arms. Magnus heard the woman’s indrawn breath as she saw her daughter’s eyes. He heard her begin to cry softly. Lucian stood beside the mother and daughter, looking deeply distressed, then crossed the floor with a suddenly determined tread.

“Let’s go, Valentine,” he said. “All this with the Whitelaws was . . . was a terrible accident. We can’t have our Circle suffering for it. We should go now. These creatures aren’t worth your time, not any of them. These werewolves are just strays who broke off from their pack. You and I will go hunting in the werewolf encampment where the real threat lies tonight. We will bring down the pack leader together.”

“Together. But tomorrow night. Come back to the house tonight?” Valentine asked in a low voice. “Jocelyn has something to tell you.”

Lucian clasped Valentine’s arm, clearly relieved. “Of course. Anything for Jocelyn. Anything for either of you. You know that.”

“My friend,” said Valentine, “I do.”

Valentine clasped Lucian’s arm in return, but Magnus saw the look Valentine gave Lucian. There was love in that look, but hate as well, and the hate was winning. It was as clear as a silvery shark’s fin in the dark waters of Valentine’s black eyes. There was death in those eyes.

Magnus was not surprised. He had seen many monsters who could love, but only a few who had let that love change them, who had been able to alchemize love for one person into kindness for many.

He remembered Valentine’s face as the Circle’s leader had cut Marian Whitelaw into bloody halves, and Magnus wondered what it would be like, living with someone like Valentine, wondered what it was like for his wife, who Marian had described as lovely. You could share your bed with a monster, lay your head on the same pillow next to a head filled with murder and madness. Magnus had done it himself.

But love that blind did not last. One day you lifted your head from the pillow and saw you were living in a nightmare.

Lucian Graymark might be the only one of the lot worth bothering with, and Magnus would bet he was as good as dead.

Magnus had been so terribly wrong to let the past deceive him; he’d been wrong to think that the one with depths of goodness in him was Stephen Herondale. Magnus looked at Stephen, at his beautiful face and his weak mouth. Magnus had a sudden impulse to tell the Shadowhunter that Magnus knew and loved his ancestor, that Tessa would be so disappointed in him. But he did not want Valentine’s Circle to remember or go after Tessa.

Magnus said nothing. Stephen Herondale had chosen his side, and Magnus had chosen his.

Valentine’s Circle withdrew from the warehouse, marching like a little army.

Magnus ran to where old Adam Whitelaw lay in a pool of blood, his shining axe lying, dull and still, in the same dark pool.
