Her hands moved restlessly as she spoke, from her gesture at the walls to plucking at her gown dyed with old, old blood. She touched her arms as if they still hurt where she had been held back by the Shadowhunters, and she toyed with a large ornate locket that hung around her neck. She opened and closed it, the tarnished metal gleaming between her fingers, and Magnus thought he saw a glimpse of a ghastly portrait. Her son again?

He looked toward the picture on the wall, the pale young face, and calculated how old a child of Rupert Blackthorn's must have been when the man had died twenty-five years before. If Jesse Blackthorn had died when he was sixteen then the boy must have been dead for nine years, but perhaps a mother's mourning never ended.

"I am aware that you have suffered greatly, Mrs. Blackthorn," said Magnus, as gently as he was able. "But instead of some plot of vengeance through the senseless slaughter of Shadowhunters, consider that there are many Shadowhunters who desire nothing more than to help you, and to ease your pain."

"Indeed? Of whom do you speak? William Herondale"-and in Tatiana's mouth hatred dripped from every syllable of Will's name-"sneered at me because all I did was scream as my beloved died, but tell me, what else could I have done? What else had I ever been taught to do?" Tatiana's eyes were huge and poison-green, eyes with enough pain in them to eat away at a world and devour a soul. "Can you tell me, warlock? Could William Herondale tell me? Can anyone tell me what I should have done, when I did everything I was ever asked to do? My husband is dead, my father is dead, my brothers are lost, my home was stolen, and the Nephilim had no power to save my son. I was everything I was ever asked to be, and as my reward my life was burned to ash. Do not speak to me of easing my pain. My pain is all that I have left. Do not speak to me of being a Shadowhunter. I am not one of them. I refuse to be."

"Very well, madam. You have made your anti-Shadowhunter position amply clear," said Magnus. "What I do not know is why you think I will help you get what you want."

Magnus was many things, but he had never been a fool. The death of a few Shadowhunters was not an aim in itself. If that were all she wanted, she would not have needed to go to Magnus.

The only reason she could have to go to a warlock was if she wanted to use those deaths, to alchemize Shadowhunter lives into magic for a spell. It would be the darkest of dark spells, and the fact that Tatiana knew of it told Magnus this was not the first time she had turned to dark magic.

What Tatiana Blackthorn, whose pain had eaten away at her like a wolf inside her breast, wanted from dark magic, Magnus did not know. He did not want to know what she had done with power in the past, and he certainly did not want her to have power that could be cataclysmic now.

Tatiana frowned a little puzzled frown that made her look like Benedict Lightwood's spoiled and cosseted daughter again.

"For money, of course."

Chapter Nine

"You imagine I would kill five people, and leave untold power in your hands," said Magnus, "for money?"

Tatiana waved a hand. "Oh, don't try to drive the price up by aping your betters and pretending that you have any morals or tender feelings, demon spawn. Name a higher sum and be done with it. The hours of the night are precious to me, and I wish to waste no further time on one such as you."

It was the casualness with which she spoke that was so chilling. Mad though Tatiana might have been, here she was not raving or bitter. She was simply working from the facts as Shadowhunters knew them: that a Downworlder must be so entirely corrupt that she did not even dream he had a heart.

Of course, of course, the vast majority of the Shadowhunters thought of him as something less than human, and as far below the children of the Angel as apes were below men. He might sometimes be useful, but he was a creature to be despised, used but then discarded, his touch avoided because it was unclean.

He had been very useful to Will Herondale, after all. Will had not come to him searching for a friend but a convenient source of magic. Even the best Shadowhunters were not so different from the rest.

"Let me say to you what I said once, in an entirely different context, to Catherine the Great," Magnus declared. "My dear lady, you cannot afford me, and also, please leave that horse alone. Good night."

He made a bow and then made his way, with some speed, out of the room. As the door shut with a snap, he heard Tatiana's voice snapping to match it: "Go after him!"

He was not surprised to hear soft footsteps pattering after him down the stairs. Magnus turned from the front door and met Grace's eyes.

Her footfalls were as light as a child's, but she did not look like a child. In that porcelain-pure face her eyes were gray hollows, deep alluring lakes with sirens in their depths. She met Magnus's eyes with a level gaze, and Magnus was reminded once again of Camille.

It was remarkable that a girl who looked no more than sixteen could rival a centuries-old vampire for self-possession. She had not had time to freeze past caring. There must, Magnus thought, be something behind all this ice.

"You will not return upstairs, I see," Grace said. "You want no part of Mama's plan."

It was not a question, and she did not sound shocked or curious. It did not seem unthinkable to her, then, that Magnus might have scruples. Perhaps the girl had qualms of conscience herself, but she was shut up here in this dark house with a madwoman, nothing but bitterness poured into her ears from dusk to daybreak. Little wonder if she was different from other girls.

Magnus felt regret suddenly for the way he had shuddered back from Grace. She was not much more than a child, after all, and nobody knew better than he what it was like to be judged and shunned. He reached out to touch her arm. "Do you have somewhere else to go?" Magnus asked her.

"Somewhere else?" said Grace. "We reside mainly in Idris."

"What I mean is, would she let you leave? Do you need help?"

Grace moved with such speed that it was as if she were a bolt of lightning wrapped in muslin, the long gleaming blade flying from her skirts to her hand. She held the glittering point against Magnus's chest, over his heart.

Here was a Shadowhunter, Magnus thought. Tatiana had learned something from the mistakes of her father. She'd had the girl trained.

"I am no prisoner here."

"No?" Magnus asked. "Then what are you?"

Grace's awful, awe-inspiring eyes narrowed. They were glittering like the steel, and were, Magnus was sure, no less deadly. "I am my mother's blade."

Shadowhunters often died young, and left children behind to be raised by others. That was nothing unusual. It was natural that such a ward, taken into a Shadowhunter's home, would think of and speak to their guardian as a parent. Magnus had thought nothing of it. Yet now it occurred to him that a child might be so grateful to be taken in that her loyalty would be fierce, that a girl raised by Tatiana Blackthorn might not wish for rescue. She might wish for nothing more than the fulfillment of her mother's dark plans.

"Are you threatening me?" Magnus said softly.

"If you do not intend to help us," she said, "then leave this house. Dawn is coming."

"I am not a vampire," Magnus said. "I shall not disappear with the light."

"You will if I kill you before the sun comes up," said Grace. "Who would miss one warlock?"

And she smiled, a wild smile that reminded him again of Camille. That potent blend of beauty and cruelty. He had fallen victim to it himself. He could only imagine again, with growing horror, what the effect would have been on James Herondale, a gentle boy who had been reared to believe that love, too, was gentle. James had given his heart to this girl, Magnus thought, and Magnus knew well enough from Edmund and Will what it meant when a Herondale gave his heart away. It was not a gift that could be returned.

Tessa, Will, and Jem had raised James in love, and had surrounded him with love and the goodness it could produce. But they had given him no armor against the evil. They had wrapped his heart in silks and velvet, and then he had given it to Grace Blackthorn, and she had spun for it a cage of razor wire and broken glass, burned it to bits, and blown away the remains, another layer of ashes in this place of beautiful horrors.

Magnus waved a hand behind his back, then stepped away from Grace's blade, away through the magically open door.

"You will tell no one of what my mother asked of you tonight," said Grace. "Or I will ensure your destruction."

"I believe you think you could," Magnus breathed. She was terrible and brilliant, like the light shining off the edge of a razor. "Oh, and by the way? I suspect that if James Herondale had known I was coming here, he would have sent his regards."

Grace lowered her sword, nothing more. Its point rested gently on the ground. Her hand did not shake, and her lashes screened her eyes. "What do I care for James Herondale?" she asked.

"I thought you might. After all, a blade does not get to choose where it is pointed."

Grace looked up. Her eyes were still, deep pools, entirely unruffled.

"A blade does not care," she told him.

Magnus turned and made his way past tangles of black roses and undergrowth down toward the rusted gates. He looked back at the manor only once, saw the wreck of what had been grand and gracious, and saw a curtain fluttering in a window high above, and the suggestion of a face. He wondered who was watching him go.

He could warn Downworlders to steer clear of Tatiana and her endeavors. No matter what the price offered, no Downworlder would fail to listen to a warning against one of the Nephilim. Tatiana would raise no dark magic.

Magnus could do that much, but he did not see a way to help James Herondale. Grace and Tatiana might have cast a spell on him, Magnus supposed. He would not put it past either of them, but he could not see why they would. What possible role could James Herondale have to play in whatever dark plot they were hatching? More likely the boy had simply fallen prey to her charms. Love was love; there was no spell to cure a broken heart that did not also destroy that heart's capacity for love forever.

And there was no reason for Magnus to tell Will and Tessa what he had learned. James's feelings for Grace were his secret to keep. Magnus had told the boy he would never betray his secrets; he had sworn it. He had never betrayed Will's confidence, and he would not betray James's now. What good would it do Will and Tessa, to know the name of their son's pain and still have no remedy for it?

He thought once more of Camille, and how it had hurt him to learn the truth about her, how he had struggled like a man crawling over knives not to know it, and finally, with even greater pain, had been forced to accept it.

Magnus did not take such suffering lightly, but even mortals did not die of broken hearts. No matter how cruel Grace had been, he told himself, James would heal. Even though he was a Herondale.

He opened the gates with his hands, thorns scratching his flesh, and he remembered again his first sight of Grace and the feeling he'd had of being faced with a predator. She was very different from Tessa, who had always steadied and anchored Will, softened his eyes into humor and his lips to gentleness.

It would be ironic, Magnus thought, terribly and cruelly ironic, for one Herondale to be saved by love, and another Herondale damned by it.

He tried to shake off both the memory of Tessa and Will and the echo of Tatiana's condemning words. He had promised Tessa that he would return, but now he found all he wanted to do was escape. He did not want to care what Shadowhunters thought of him. He did not want to care what would become of them or their children.

He had offered help to three Shadowhunters this night. One of them had replied that he was beyond help, one had asked him to commit murder, and one had pointed a blade at him.

His relationship of mutual distant tolerance with the Whitelaws of the New York Institute seemed suddenly alluring. He was part of Downworld New York, and would have it no other way. He was glad he had left London. He discovered in himself a pang for New York and its brighter lights, and fewer broken hearts.

"Where to?" asked the driver.

Magnus thought of the ship from Southampton to New York, of standing on the deck of the boat, letting the sea air wash him clean of the musty air of London. He said, "I believe I am going home.
