Gabriel glared at his older brother, who was standing quite peaceably with Sophie, but obediently turned his attention from Will to the day's training.

They were practicing how to hold blades today, and how to balance them as they swept them through the air without the blade point drooping forward or the handle slipping from the hand. It was harder than it looked, and today Gabriel wasn't patient. She envied Sophie, being taught by Gideon, who was always a careful, methodical instructor, though he did have a habit of slipping into Spanish whenever Sophie did something wrong. "A y Dios mio," he would say, pul ing the blade from where it had stuck, point down, in the floor.

"Shal we try that again?"

"Stand up straight," Gabriel was saying to Tessa meanwhile, impatiently.

"No, straight. Like this." He demonstrated. She wanted to snap at him that she, unlike him, had not had a lifetime of being taught how to stand and move; that Shadowhunters were natural acrobats, and she was nothing of the sort.

"Hmph," she said. "I'd like to see you learn how to manage sitting and standing up straight in stays and petticoats and a dress with a foot's worth of train!"

"So would I," said Gideon from across the room.

"Oh, by the Angel," said Gabriel, and he took her by the shoulders, flipping her around so she stood with her back to him. He put his arms around her, straightening her spine, arranging the knife in her hand. She could feel his breath on the back of her neck, and it made her shiver-and fil ed her with annoyance. If he was touching her, it was only because he presumed he could, without asking, and because he thought it would irritate Will.

"Let me go," she said, under her breath.

"This is part of your training," said Gabriel in a bored voice. "Besides, look at my brother and Miss Col ins. She isn't complaining."

She glanced across the room at Sophie, who seemed earnestly engaged in her lesson with Gideon. He was standing behind her, one arm around her from the back, showing her how to hold a needle-tipped throwing knife. His hand was gently cupped around hers, and he appeared to be speaking to the back of her neck, where her dark hair had escaped from its tight chignon and curled becomingly. When he saw Tessa looking at them, he flushed.

Tessa was amazed. Gideon Lightwood, blushing! Had he been admiring Sophie? Apart from her scar, which Tessa barely noticed anymore, she was lovely, but she was a mundane, and a servant, and the Lightwoods were awful snobs. Tessa's insides felt suddenly tight. Sophie had been treated abominably by her previous employer. The last thing she needed was some pretty Shadowhunter boy taking advantage of her.

Tessa looked around, about to say something to the boy with his arms around her-and stopped. She had forgotten that it was Gabriel beside her, not Jem. She had grown so used to Jem's presence, the ease with which she could converse with him, the comfort of his hand on her arm when they walked, the fact that he was the only person in the world now she felt she could say absolutely anything to. She realized with surprise that though she had just seen him at breakfast, she missed him, with what felt almost like an ache inside.

She was so caught up in this mixture of feelings-missing Jem, and a sense of passionate protectiveness over Sophie-that her next throw went wide by several feet, flying by Gideon's head and bouncing off the windowsill.

Gideon looked calmly from the fal en knife to his brother. Nothing seemed to bother him, not even his own near decapitation. "Gabriel, what is the problem, exactly?"

Gabriel turned his gaze on Tessa. "She won't listen to me," he said spiteful y. "I can't instruct someone who won't listen."

"Maybe if you were a better instructor, she'd be a better listener."

"And maybe you would have seen the knife coming," said Gabriel, "if you paid more attention to what's going on around you and less to the back of Miss Col ins's head."

So even Gabriel had noticed, Tessa thought, as Sophie blushed. Gideon gave his brother a long, steady look-she sensed there would be words between the two of them at home-then turned to Sophie and said something in a low voice, too low for Tessa to hear.

"What's happened to you?" she said under her breath to Gabriel, and felt him stiffen.

"What do you mean?"

"You're usual y patient," she said. "You're a good teacher, Gabriel, most of the time, but today you're snappish and impatient and . . ." She looked down at his hand on her arm. "Improper."

He had the good grace to release her, looking ashamed of himself. "A thousand pardons. I should not have touched you like that."

"No, you shouldn't. And after the way you criticize Will -"

He flushed along his high cheekbones. "I've apologized, Miss Gray. What more do you want of me?"

"A change in behavior, perhaps. An explanation of your dislike of Will -"

"I've told you! If you wish to know why I dislike him, you can ask him yourself!" Gabriel whirled and stalked out of the room.

Tessa looked at the knives stuck into the wal and sighed. "So ends my lesson."

"Try not to be too put out," said Gideon, approaching her with Sophie by his side. It was very odd, Tessa thought; Sophie usual y seemed uneasy around men, any men, even gentle Henry. With Will she was like a scalded cat, and with Jem, blushing and watchful, but beside Gideon she seemed . . .

Well, it was hard to define. But it was most peculiar.

"It is not your fault he is like this today," Gideon went on. His eyes on Tessa were steady. This close up she could see that they were not precisely the same color as his brother's. They were more of a gray-green, like the ocean under a cloudy sky. "Things have been . . . difficult for us at home with Father, and Gabriel is taking it out on you, or, real y, anyone who happens to be nearby."

"I'm most sorry to hear that. I hope your father is well," murmured Tessa, praying she would not be stricken down on the spot for this blatant falsehood.

"I suppose I had better go after my brother," said Gideon without answering her question. "If I do not, he Will take the carriage and leave me stranded. I hope to have him back to you at our next session in a better humor." He bowed to Sophie, then Tessa. "Miss Col ins, Miss Gray."

And he was gone, leaving both girls looking after him in mingled confusion and surprise.

With the training session merciful y over, Tessa found herself hurrying to change back into her ordinary clothes, and then to lunch, eager to see if Will had returned. He hadn't. His chair, between Jessamine and Henry, still sat empty-but there was someone new in the room, someone who made Tessa stop short at the doorway, trying not to stare. A tal man, he sat near the head of the table beside Charlotte, and was green. Not a very dark green -his skin had a faint greenish sheen to it, like light reflecting off the ocean, and his hair was snowy white. From his forehead curled two smal elegant horns.

"Miss Tessa Gray," said Charlotte, making the introductions, "this is the High Warlock of London, Ragnor Fell. Mr. Fell, Miss Gray."

After murmuring that she was delighted to meet him, Tessa sat down at the table beside Jem, diagonal y from Fell, and tried not to stare at him out of the corner of her eye. As Magnus's cat's eyes were his warlock's mark, Fel 's would be his horns and tinted skin. She couldn't help being fascinated by Downworlders still, warlocks in particular. Why were they marked and she wasn't?

"What's on the carpet, then, Charlotte?" Ragnor was saying. "Did you real y call me out here to discuss dark doings on the Yorkshire moors? I was under the impression that nothing of great interest ever happened in Yorkshire. In fact, I was under the impression that there was nothing in Yorkshire except sheep and mining."

"So you never knew the Shades?" Charlotte inquired. "The warlock population of Britain is not so large . . ."

"I knew them." As fell sawed into the ham on his plate, Tessa saw that he had an extra joint to each finger. She thought of Mrs. Black, with her elongated taloned hands, and repressed a shudder. "Shade was a little mad, with his obsession with clockwork and mechanisms. Their death was a shock to Downworld. The ripples of it went through the community, and there was even some discussion of vengeance, though none, I believe, was ever taken."

Charlotte leaned forward. "Do you remember their son? Their adopted child?"

"I knew of him. A married warlock couple is rare. One who adopts a human child from an orphanage is rarer still. But I never saw the boy. Warlocks-we live forever. A gap of thirty, even fifty, years between meetings is not unusual.

Of course now that I know what the boy grew up to be, I wish I had met him.

Do you think there is value in attempting to discover who his true parents were?"

"Certainly, if it can be discovered. Whatever information we can glean about Mortmain could be useful."

"I can tell you he gave himself that name," said Fell. "It sounds like a Shadowhunter name. It is the sort of name someone with a grudge against Nephilim, and a dark sense of humor, would take. Mort main-"

"Hand of death," supplied Jessamine, who was proud of her French.

"It does make one wonder," said Tessa. "If the Clave had simply given Mortmain what he wanted-reparations-would he still have become what he did? Would there ever have been a Pandemonium Club at all?"

"Tessa-," Charlotte began, but Ragnor fell waved her silent. He gazed amusedly down the table at Tessa. "You're the shape-changer, aren't you?"

he said. "Magnus Bane told me about you. No mark on you at all, they say."

Tessa swal owed and looked him straight in the eye. They were discordantly human eyes, ordinary in his extraordinary face. "No. No mark."

He grinned around his fork. "I do suppose they've looked everywhere?"

"I'm sure Will 's tried," said Jessamine in a bored tone. Tessa's silverware clattered to her plate. Jessamine, who had been mashing her peas flat with the side of her knife, looked up when Charlotte let out an aghast, "Jessamine!"

Jessamine shrugged. "Well, he's like that."

Fel turned back to his plate with a faint smile on his face. "I remember Will 's father. Quite the ladies' man, he was. They couldn't resist him. Until he met Will 's mother, of course. Then he threw it all in and went to live in Wales just to be with her. What a case he was."

"He fell in love," said Jem. "It isn't that peculiar."

"'Fel ' into it," said the warlock, still with the same faint smile. "Hurtled into it is more like. Headlong-crashed into it. Still, there are always some men like that-just one woman for them, and only she Will do, or nothing."

Charlotte looked over at Henry, but he appeared completely lost in thought, counting something-though who knew what-off on his fingers. He was wearing a pink and violet waistcoat today, and had gravy on his sleeve.

Charlotte's shoulders slumped visibly, and she sighed. "Well," she said. "By all accounts they were very happy together-"

"Until they lost two of their three children and Edmund Herondale gambled away everything they had," said Fell. "But I imagine you never told young Will about that."

Tessa exchanged a glance with Jem. My sister is dead, Will had said.

"They had three children, then?" she said. "Wil had two sisters?"

"Tessa. Please." Charlotte looked uneasy. "Ragnor . . . I never hired you to invade the privacy of the Herondales, or Will. I did it because I had promised Will I would tell him if harm came to his family."

Tessa thought of Will -a twelve-year-old Will, clinging to Charlotte's hand, begging to be told if his family died. Why run? she thought for the hundredth time. Why put them behind you? She had thought perhaps he did not care, but clearly he had cared. Cared still. She could not stop the tightening at her heart as she thought of him call ing out for his sister. If he loved Cecily as she had once loved Nate . . .

Mortmain had done something to his family, she thought. As he had to hers. That bound them to each other in a peculiar way, she and Will. Whether he knew it or not.

"Whatever it is that Mortmain has been planning," she heard herself say, "he has been planning it a long time. Since before I was born, when he tricked or coerced my parents into 'making' me. And now we know that years ago he involved himself with Will 's family and moved them to Ravenscar Manor. I fear we are like chess pieces he slides about a board, and the outcome of the game is already known to him."

"That is what he desires us to think, Tessa," said Jem. "But he is only a man. And each discovery we make about him makes him more vulnerable. If we were no threat, he would not have sent that automaton to warn us off."

"He knew exactly where we would be-"

"There is nothing more dangerous than a man bent on revenge," said Ragnor. "A man who has been bent on it for nearly three score years, who has nurtured it from a tiny, poisonous seed to a living, choking flower. He Will see it through, unless you end him first."

"Then, we Will end him," said Jem shortly. It was as close to a threat as Tessa had ever heard him make.

Tessa looked down at her hands. They were a paler white than they had been when she lived in New York, but they were her hands, familiar, the index finger slightly longer than the middle one, the half-moons of her nails pronounced. I could Change them, she thought. I could become anything, anyone. She had never felt more mutable, more fluid, or more lost.

"Indeed." Charlotte's tone was firm. "Ragnor, I want to know why the Herondale family is in that house-that house that belonged to Mortmain- and I want to see to it that they are safe. And I want to do it without Benedict Lightwood or the rest of the Clave hearing about it."

"I understand. You want me to look out for them as quietly as possible while also making inquiries regarding Mortmain in the area. If he moved them there, it must have been for a purpose."

Charlotte exhaled. "Yes."

Ragnor twirled his fork. "That Will be expensive."

"Yes," Charlotte said. "I am prepared to pay."

Fel grinned. "Then, I am prepared to endure the sheep."

The rest of the lunch passed in awkward conversation, with Jessamine moodily destroying her food without eating it, Jem unusual y quiet, Henry muttering equations to himself, and Charlotte and fell finalizing their plans for the protection of Will 's family. As much as Tessa approved of the idea-and she did-there was something about the warlock that made her uncomfortable in a way Magnus never had, and she was glad when lunch was over and she could escape to her room with a copy of The Tenant of Wildfell Hall.
