The carriage swung out of a narrow street and into a huge square; Tessa drew in a breath. Before them rose a magnificent cathedral, its Gothic turrets piercing the gray sky like Saint Sebastian stuck through with arrows. A massive limestone tower surmounted the structure, and niches along the front of the building held sculpted statues, each one different. "Is that the Institute? Goodness, it's so much grander than London's-"

Will laughed. "Sometimes a church is only a church, Tess."

"That's York Minster," said Jem. "Pride of the city. Not the Institute. The Institute's in Goodramgate Street." His words were confirmed as the carriage swung away from the cathedral, down Deangate, and onto the narrow, cobbled lane of Goodramgate, where they rattled beneath a smal iron gate between two leaning Tudor buildings.

When they emerged on the other side of the gate, Tessa saw why Will had laughed. What rose before them was a pleasant-enough-looking church, surrounded by enclosing wal s and smooth grass, but it had none of the grandeur of York Minster. When Gottshal came around to swing the door of the carriage open and help Tessa down to the ground, she saw that occasional headstones rose from the rain-dampened grass, as if someone had intended to begin a cemetery here and had lost interest halfway through the proceedings.

The sky was nearly black now, silvered here and there with clouds made near-transparent by starlight. Behind her, Jem's and Will 's familiar voices murmured; before her, the doors of the church stood open, and through them she could see flickering candles. She felt suddenly bodiless, as if she were the ghost of Tessa, haunting this odd place so far from the life she had known in New York. She shivered, and not just from the cold.

She felt the brush of a hand against her arm, and warm breath stirred her hair. She knew who it was without turning. "Shal we go in, my betrothed?"

Jem said softly in her ear. She could feel the laughter in him, vibrating through his bones, communicating itself to her. She almost smiled. "Let us beard the lion in his den together."

She put her hand through his arm. They made their way up the steps of the church; she looked back at the top, and saw Will gazing up after them, apparently unheeding as Gottshal tapped him on the shoulder, saying something into his ear. Her eyes met his, but she looked quickly away; entangling gazes with Will was confusing at best, dizzying at worst.

The inside of the church was smal and dark compared to the London Institute's. Pews dark with age ran the length of the wal s, and above them witchlight tapers burned in holders made of blackened iron. At the front of the church, in front of a veritable cascade of burning candles, stood an old man dressed all in Shadowhunter black. His hair and beard were thick and gray, standing out wildly around his head, his gray-black eyes half-hidden beneath massive eyebrows, his skin scored with the marks of age. Tessa knew him to be almost ninety, but his back was still straight, his chest as thick around as the trunk of a tree.

"Young Herondale, are you?" he barked as Will stepped forward to introduce himself. "Half-mundane, half-Welsh, and the worst traits of both, I've heard."

Will smiled politely. "Diolch."

Starkweather bristled. "Mongrel tongue," he muttered, and turned his gaze to Jem. "James Carstairs," he said. "Another Institute brat. I've half a mind to tel the lot of you to go to blazes. That upstart bit of a girl, that Charlotte Fairchild, foisting you all on me with nary a by-your-leave." He had a little of the Yorkshire accent that his servant had, though much fainter; still, the way he pronounced "I" did sound a bit like "Ah." "None of that family ever had a bit o' manners. I could do without her father, and I can do without-"

His flashing eyes came to rest on Tessa then, and he stopped abruptly, his mouth open, as if he had been slapped in the face midsentence. Tessa glanced at Jem; he looked as startled as she did at Starkweather's sudden silence. But there, in the breach, was Will.

"This is Tessa Gray, sir," he said. "She is a mundane girl, but she is the betrothed of Carstairs here, and an Ascendant."

"A mundane, you say?" demanded Starkweather, his eyes wide.

"An Ascendant," said Will in his most soothing, silken voice. "She has been a faithful friend to the Institute in London, and we hope to welcome her into our ranks soon."

"A mundane," the old man repeated, and broke into a fit of coughing. "Well, times have-Yes, I suppose then-" His eyes skipped across Tessa's face again, and he turned to Gottshall, who was looking martyred among the luggage. "Get Cedric and Andrew to help you bring our guests' belongings up to their rooms," he said. "And do tell El en to instruct Cook to set three extra places for dinner tonight. I may have forgotten to remind her that we would have guests."

The servant gaped at his master before nodding in a seeming daze; Tessa couldn't blame him. It was clear that Starkweather had meant to send them packing and had changed his mind at the last moment. She glanced at Jem, who looked just as mystified as she felt; only Will, blue eyes wide and face as innocent as a choirboy's, seemed as if he had expected nothing else.

"Well, come along, then," said Starkweather gruffly without looking at Tessa. "You needn't stand there. Fol ow me and I'll show you to your rooms."

"By the Angel," Will said, scraping his fork through the brownish mess on his plate. "What is this stuff?"

Tessa had to admit, it was difficult to tell. Starkweather's servants-mostly bent old men and women and a sour-faced female housekeeper-had done as he'd asked and had set three extra places for supper, which consisted of a dark, lumpy stew ladled out of a silver tureen by a woman in a black dress and white cap, so bent and old that Tessa had to physical y prevent herself from leaping up to assist her with the serving. When the woman was done, she turned and shuffled off, leaving Jem, Tessa, and Will alone in the dining room to stare at one another across the table.

A place had been set for Starkweather as well, but he wasn't at it. Tessa had to admit that if she were him, she wouldn't be rushing to eat the stew either. Heavy with overcooked vegetables and tough meat, it was even more unappetizing-looking in the dim light of the dining room. Only a few tapers lit the cramped space; the wal paper was dark brown, the mirror over the unlit hearth stained and discolored. Tessa felt dreadful y uncomfortable in her evening dress, a stiff blue taffeta borrowed from Jessamine and let out by Sophie, which had turned to the color of a bruise in the unhealthy light.

Still, it was awful y peculiar behavior for a host, to be so insistent that they join him for supper and then not to appear. A servant just as frail and ancient as the one who'd ladled out the stew had led Tessa to her room earlier, a great dim cavern full of heavy carved furniture. It too was dimly lit, as if Starkweather were trying to save money on oil or tapers, though as far as Tessa knew, witchlight cost nothing. Perhaps he simply liked the dark.

She had found her room chil y, dark, and more than slightly ominous. The low fire burning in the grate had done little to warm the room. On either side of the hearth was carved a jagged lightning bolt. The same symbol was on the white pitcher full of chil y water that Tessa had used to wash her hands and face. She had dried off quickly, wondering why she couldn't remember the symbol from the Codex. It must mean something important. The whole of the London Institute was decorated with Clave symbols like the Angel rising from the lake, or the interlocked Cs of Council, Covenant, Clave, and Consul.

Heavy old portraits were everywhere as well -in her bedroom, in the corridors, lining the staircase. After changing into evening dress and hearing the dinner bel ring, Tessa had made her way down the staircase, a great carved Jacobean monstrosity, only to pause on the landing to gaze at the portrait of a very young girl with long, fair hair, dressed in an old-fashioned child's dress, a great ribbon surmounting her smal head. Her face was thin and pale and sickly, but her eyes were bright-the only bright thing in this dark place, Tessa had thought.

"Adele Starkweather," had come a voice at her elbow, reading off the placard on the portrait's frame. "1842."

She had turned to look at Will, who'd stood with his feet apart, his hands behind his back, gazing at the portrait and frowning.

"What is it? You look as if you don't like her, but I rather do. She must be Starkweather's daughter-no, granddaughter, I think."

Will had shaken his head, looking from the portrait to Tessa. "No doubt.

This place is decorated like a family home. It is clear there have been Starkweathers in the York Institute for generations. You've seen the lightning bolts everywhere?"

Tessa had nodded.

"That is the Starkweather family symbol. There is as much of the Starkweathers here as there is of the Clave. It is bad form to behave as if one owns a place like this. One cannot inherit an Institute. The guardian of an Institute is appointed by the Consul. The place itself belongs to the Clave."

"Charlotte's parents ran the London Institute before she did."

"Part of the reason old Lightwood is so tinder-tempered about the whole business," Will had replied. "Institutes aren't necessarily meant to stay in families. But the Consul wouldn't have given Charlotte the post if he hadn't thought she was the right person for it. And it's only one generation. This-"

He swept his arm about as if to encompass the portraits, the landing, and odd, lonely Aloysius Starkweather, all in one gesture. "Well, no wonder the old man thinks he has the right to throw us out of the place."

"Mad as hops, my aunt would have said. shall we go down to dinner?"

In a rare show of gentility, Will had offered his arm. Tessa hadn't looked at him as she'd taken it. Will dressed for dinner was handsome enough to take away her breath, and she'd had the feeling she'd need her wits about her.

Jem had already been waiting in the dining room when they'd arrived, and Tessa had settled herself beside him to await their host. His place had been set, his plate fil ed with stew, even his wineglass fil ed with dark red wine, but there had been no sign of him. It was Will who had shrugged first and begun to eat, though he'd soon looked as if he wished he hadn't.

"What is this?" he went on now, spearing an unfortunate object on a fork and raising it to eye level. "This . . . this . . . thing?"

"A parsnip?" Jem suggested.

"A parsnip planted in Satan's own garden," said Will. He glanced about. "I don't suppose there's a dog I could feed it to."

"There don't seem to be any pets about," Jem-who loved all animals, even the inglorious and il -tempered Church-observed.

"Probably all poisoned by parsnips," said Will.

"Oh, dear," Tessa said sadly, laying her fork down. "And I was so hungry too."

"There's always the dinner rol s," said Will, pointing to a covered basket.

"Though I warn you, they're as hard as stones. You could use them to kil black beetles, if any beetles bother you in the middle of the night."

Tessa made a face and took a swig of her wine. It was as sour as vinegar.

Will set his fork down and began cheerful y, in the manner of Edward Lear's Book of Nonsense: "There once was a lass from New York Who found herself hungry in York.

But the bread was like rocks, The parsnips shaped like-"

"You can't rhyme 'York' with 'York,'" interrupted Tessa. "It's cheating."

"She's right, you know," said Jem, his delicate fingers playing with the stem of his wineglass. "Especial y with 'fork' being so obviously the correct choice-"

"Good evening." The hulking shadow of Aloysius Stark-weather loomed up suddenly in the doorway; Tessa wondered with a flush of embarrassment how long he'd been standing there. "Mr. Herondale, Mr. Carstairs, Miss, ah -"

"Gray," Tessa said. "Theresa Gray."

"Indeed." Starkweather made no apologies, just settled himself heavily at the head of the table. He was carrying a square, flat box, the sort bankers used to keep their papers in, which he set down beside his plate. With a flash of excitement Tessa saw that there was a year marked on it-1825- and even better, three sets of initials. JTS, A ES, A HM.

"No doubt your young miss Will be pleased to know I've buckled to her demands and searched the archives all day and half last night besides,"

Starkweather began in an aggrieved tone. It took Tessa a moment to realize that in this case, "young miss" meant Charlotte. "It's lucky, she is, that my father never threw anything out. And the moment I saw the papers, I remembered." He tapped his temple. "Eighty-nine years, and I never forget a thing. You tell old Wayland that when he talks about replacing me."

"We surely will, sir," said Jem, his eyes dancing.

Starkweather took a hearty gulp of his wine and made a face. "By the Angel, this stuff's disgusting." He set the glass down and began pul ing papers from the box. "What we have here is an application for Reparations on behalf of two warlocks. John and Anne Shade. A married couple.

"Now, here's the odd bit," the old man went on. "The filing was done by their son, Axel Hol ingworth Mortmain, twenty-two years old. Now, of course warlocks are barren-"

Will shifted uncomfortably in his seat, his eyes slanting away from Tessa's.

"This son was adopted," said Jem.

"Shouldn't be all owed, that," said Starkweather, taking another slug of the wine he had pronounced disgusting. His cheeks were beginning to redden.

"Like giving a human child to wolves to raise. Before the Accords-"

"If there are any clues to his whereabouts," said Jem, gently trying to steer the conversation back onto its track. "We have very little time-"

"Very well, very well," snapped Starkweather. "There's little information about your precious Mortmain in here. More about the parents. It seems suspicion fell on them when it was discovered that the male warlock, John Shade, was in possession of the Book of the White. Quite a powerful spel book, you understand; disappeared from the London Institute's library under suspicious circumstances back in 1752. The book specializes in binding and unbinding spel s-tying the soul to the body, or untying it, as the case may be. Turned out the warlock was trying to animate things. He was digging up corpses or buying them off medical students and replacing the more damaged bits with mechanisms. Then trying to bring them to life.

Necromancy-very much against the Law. And we didn't have the Accords in those days. An Enclave group swept in and slaughtered both warlocks."
