I sat as far from Knox as possible, perched on a straight-backed wooden chair usually reserved for disgraced junior members of the college.

Knox and I remained silent while Marsh murmured and tutted into the phone. He punched a b.u.t.ton on the console and approached me, a gla.s.s of sherry in his hand. "That's the vice-chancellor. Two freshers have gone missing," he said, using the university's slang term for new students. "You two chat while I deal with this in my study. Please excuse me."

Distant doors opened and closed, and m.u.f.fled voices conferred in the hall before there was silence.

"Missing students?" I said blandly. Surely Knox had magically engineered both the crisis and the phone call that had drawn Marsh away.

"I don't understand, Dr. Bishop," Knox murmured. "It seems unfortunate for the university to misplace two children. Besides, this gives us a chance to talk privately."

"What do we have to talk about?" I sniffed my sherry and prayed for the warden's return.

"A great many things."

I glanced at the door.

"Nicholas will be quite busy until we're through."

"Let's get this over with, then, so that the warden can return to his drink."

"As you wish," Knox said. "Tell me what brought you to Oxford, Dr. Bishop."

"Alchemy." I would answer the man's questions, if only to get Marsh back into the room, but wasn't going to tell him more than was necessary.

"You must have known that Ashmole 782 was bewitched. No one with even a drop of Bishop blood in her veins could have failed to notice. Why did you send it back?" Knox's brown eyes were sharp. He wanted the ma.n.u.script as much as Matthew Clairmont did-if not more.

"I was done with it." It was difficult to keep my voice even.

"Was there nothing about the ma.n.u.script that piqued your interest?"

"Nothing."

Peter Knox's mouth twisted into an ugly expression. He knew I was lying. "Have you shared your observations with the vampire?"

"I take it you mean Professor Clairmont." When creatures refused to use proper names, it was a way of denying that those who were not like you were your equals.

Knox's fingers unwound once more. When I thought he might point them at me, he curled them around the arms of his chair instead. "We all respect your family and what you've endured. Nevertheless, questions have been raised about your unorthodox relationship with this creature. You are betraying your ancestral lineage with this self-indulgent behavior. It must stop."

"Professor Clairmont is a professional colleague," I said, steering the conversation away from my family, "and I know nothing about the ma.n.u.script. It was in my possession for a matter of minutes. Yes, I knew it was under a spell. But that was immaterial to me, since I'd requested it to study the contents."

"The vampire has wanted that book for more than a century," Knox said, his voice vicious. "He mustn't be allowed to have it."

"Why?" My voice crackled with suppressed anger. "Because it belongs to the witches? Vampires and daemons can't enchant objects. A witch put that book under a spell, and now it's back under the same spell. What are you worried about?"

"More than you could possibly comprehend, Dr. Bishop."

"I'm confident I can keep up, Mr. Mr. Knox," I replied. Knox's mouth tightened with displeasure when I emphasized his position outside the academy. Every time the wizard used my t.i.tle, his formality sounded like a taunt, as if he were trying to make a point that he, not I, was the real expert. I might not use my power, and I couldn't have conjured up my own lost keys, but being patronized by this wizard was intolerable. Knox," I replied.

"I am disturbed that you-a Bishop-are a.s.sociating with a vampire." He held up his hand as a protest bubbled to my lips. "Let's not insult each other with further untruths. Instead of the natural revulsion you should feel for that animal, you feel grat.i.tude."

I remained silent, seething.

"And I'm concerned because we are perilously close to catching human attention," he continued.

"I tried to get the creatures out of the library."

"Ah, but it's not just the library, is it? A vampire is leaving drained, bloodless corpses around Westminster. The daemons are unusually restless, vulnerable as ever to their own madness and the swings of energy in the world. We can't afford to be noticed."

"You told the reporters that there was nothing supernatural about those deaths."

Knox looked incredulous. "You don't expect me to tell humans humans everything ?" everything ?"

"I do, actually, when they're paying you."

"You're not only self-indulgent, you're foolish. That surprises me, Dr. Bishop. Your father was known for his good sense."

"I've had a long day. Is that all?" Standing abruptly, I moved toward the door. Even in normal circ.u.mstances, it was difficult to listen to anyone but Sarah and Em talking about my parents. Now-after Gillian's revelations-there was something almost obscene about it.

"No, it is not," said Knox unpleasantly. "What I am most intrigued by, at present, is the question of how an ignorant witch with no training of any sort managed to break a spell that has defied the efforts of those far more adept than you will ever be."

"So that's why you're all watching me." I sat down, my back pressing against the chair's slats.

"Don't look so pleased with yourself," he said curtly. "Your success may have been a fluke-an anniversary reaction related to when the spell was first cast. The pa.s.sage of time can interfere with witchcraft, and anniversaries are particularly volatile moments. You haven't tried to recall it yet, but when you do, it may not come as easily as it did the first time."

"And what anniversary would we be celebrating?"

"The sesquicentennial."

I had wondered why a witch would put a spell on the ma.n.u.script in the first place. Someone must have been looking for it all those years ago, too. I blanched.

We were back to Matthew Clairmont and his interest in Ashmole 782.

"You are are managing to keep up, aren't you? The next time you see your vampire, ask him what he was doing in the autumn of 1859. I doubt he'll tell you the truth, but he might reveal enough for you to figure it out on your own." managing to keep up, aren't you? The next time you see your vampire, ask him what he was doing in the autumn of 1859. I doubt he'll tell you the truth, but he might reveal enough for you to figure it out on your own."

"I'm tired. Why don't you tell me, witch to witch, what your your interest is in Ashmole 782?" I'd heard why the daemons wanted the ma.n.u.script. Even Matthew had given me some explanation. Knox's fascination with it was a missing piece of the puzzle. interest is in Ashmole 782?" I'd heard why the daemons wanted the ma.n.u.script. Even Matthew had given me some explanation. Knox's fascination with it was a missing piece of the puzzle.

"That ma.n.u.script belongs to us," Knox said fiercely. "We're the only creatures who can understand its secrets and the only creatures who can be trusted to keep them."

"What is in the ma.n.u.script? " I said, temper flaring at last. " I said, temper flaring at last.

"The first spells ever constructed. Descriptions of the enchantments that bind the world together." Knox's face grew dreamy. "The secret of immortality. How witches made the first daemon. How vampires can be destroyed, once and for all." His eyes pierced mine. "It's the source of all our power, past and present. It cannot be allowed to fall into the hands of daemons or vampires-or humans."

The events of the afternoon were catching up with me, and I had to press my knees together to keep them from shaking. "n.o.body would put all that information in a single book."

"The first witch did," Knox said. "And her sons and daughters, too, down through time. It's our history, Diana. Surely you want to protect it from prying eyes."

The warden entered the room as if he'd been waiting by the door. The tension was suffocating, but he seemed blissfully unaware of it.

"What a palaver over nothing." Marsh shook his white head. "The freshers illegally obtained a punt. They were located, stuck under a bridge and a little worse for wine, utterly content with their situation. A romance may result."

"I'm so glad," I murmured. The clocks struck forty-five minutes past the hour, and I stood. "Is that the time? I have a dinner engagement."

"You won't be joining us for dinner?" the warden asked with a frown. "Peter has been looking forward to talking to you about alchemy."

"Our paths will cross again. Soon," Knox said smoothly. "My visit was such a surprise, and of course the lady has better things to do than have dinner with two men our age."

Be careful with Matthew Clairmont. Knox's voice rang in my head. Knox's voice rang in my head. He's a killer. He's a killer.

Marsh smiled. "Yes, of course. I do hope to see you again-when the freshers have settled down."

Ask him about 1859. See if he'll share his secrets with a witch.

It's hardly a secret if you know it. Surprise registered on Knox's face when I replied to his mental warning in kind. It was the sixth time I'd used magic this year, but these were surely extenuating circ.u.mstances. Surprise registered on Knox's face when I replied to his mental warning in kind.

"It would be a pleasure, Warden. And thank you again for letting me stay in college this year." I nodded to the wizard. "Mr. Knox."

Fleeing from the warden's lodgings, I turned toward my old refuge in the cloisters and walked among the pillars until my pulse stopped racing. My mind was occupied with only one question: what to do now that two witches-my own people-had threatened me in the s.p.a.ce of a single afternoon. With sudden clarity I knew the answer.

In my rooms I searched my bag until my fingers found Clairmont's crumpled business card, and then I dialed the first number.

He didn't answer.

After a robotic voice indicated that it was ready to receive my message, I spoke.

"Matthew, it's Diana. I'm sorry to bother you when you're out of town." I took a deep breath, trying to dispel some of the guilt a.s.sociated with my decision not to tell Clairmont about Gillian and my parents, but only about Knox. "We need to talk. Something has happened. It's that wizard from the library. His name is Peter Knox. If you get this message, please call me."

I'd a.s.sured Sarah and Em that no vampire would meddle in my life. Gillian Chamberlain and Peter Knox had changed my mind. With shaking hands I lowered the shades and locked the door, wishing I'd never heard of Ashmole 782.

Chapter 11.

That night, sleep was impossible. I sat on the sofa, then on the bed, the phone at my side. Not even a pot of tea and a raft of e-mail took my mind off the day's events. The notion that witches might have murdered my parents was beyond my comprehension. Pushing back those thoughts, I instead puzzled over the spell on Ashmole 782 and Knox's interest in it.

Still awake at dawn, I showered and changed. The idea of breakfast was uncharacteristically unappetizing. Rather than eat, I perched by the door until the Bodleian opened, then walked the short distance to the library and took my regular seat. My phone was in my pocket, set to vibrate, even though I hated it when other people's phones started buzzing and hopping in the quiet.

At half past ten, Peter Knox strolled in and sat at the opposite end of the room. On the premise of returning a ma.n.u.script, I walked back to the call desk to make sure that Miriam was still in the library. She was-and she was angry.

"Tell me that witch didn't take a seat down there."

"He did. He keeps staring at my back while I work."

"I wish I were larger," Miriam said with a frown.

"Somehow I think it would take more than size to deter that creature." I gave her a lopsided smile.

When Matthew came into the Selden End, without warning or sound, no icy patches announced his arrival. Instead there were touches of snowflakes all along my hair, shoulders, and back, as if he were checking quickly to make sure I was all in one piece.

My fingers gripped the table in front of me. For a few moments, I didn't dare turn in case it was simply Miriam. When I saw it was indeed Matthew, my heart gave a single loud thump.

But the vampire was no longer looking in my direction. He was staring at Peter Knox, his face ferocious.

"Matthew," I called softly, rising to my feet.

He dragged his eyes from the witch and strode to my side. When I frowned uncertainly at his fierce expression, he gave me a rea.s.suring smile. "I understand there's been some excitement." He was so close that the coolness of his body felt as refreshing as a breeze on a summer day.

"Nothing we couldn't handle," I said evenly, conscious of Peter Knox.

"Can our conversation wait-just until the end of the day?" he asked. Matthew's fingers strayed up to touch a b.u.mp on his sternum that was visible under the soft fibers of his sweater. I wondered what he was wearing, close to his heart. "We could go to yoga."

Though I'd had no sleep, a drive to Woodstock in a moving vehicle with very good sound insulation, followed by an hour and a half of meditative movement, sounded perfect.

"That would be wonderful," I said sincerely.

"Would you like me to work here, with you?" he asked, leaning toward me. His scent was so powerful it was dizzying.

"That's not necessary," I said firmly.

"Let me know if you change your mind. Otherwise I'll see you outside Hertford at six." Matthew held my eyes a few moments longer. Then he sent a look of loathing in Peter Knox's direction and returned to his seat.

When I pa.s.sed his desk on the way to lunch, Matthew coughed. Miriam slammed her pencil down in irritation and joined me. Knox would not be following me to Blackwell's. Matthew would see to that.

The afternoon dragged on interminably, and it was almost impossible to stay awake. By five o'clock, I was more than ready to leave the library. Knox remained in the Selden End, along with a motley a.s.sortment of humans. Matthew walked me downstairs, and my spirits lightened as I raced back to college, changed, and picked up my yoga mat. When his car pulled up to Hertford's metal railings, I was waiting for him.

"You're early," he observed with a smile, taking my mat and putting it into the trunk. Matthew breathed in sharply as he helped me into the car, and I wondered what messages my body had pa.s.sed on to him.

"We need to talk."

"There's no rush. Let's get out of Oxford first." He closed the car door behind me and climbed into the driver's seat.

The traffic on the Woodstock Road was heavier due to the influx of students and dons. Matthew maneuvered deftly around the slow spots.

"How was Scotland?" I asked as we cleared the city limits, not caring what he talked about so long as he talked.

Matthew glanced at me and returned his eyes to the road. "Fine."

"Miriam said you were hunting."

He exhaled softly, his fingers rising to the b.u.mp under his sweater. "She shouldn't have."

"Why?"

"Because some things shouldn't be discussed in mixed company," he said with a touch of impatience. "Do witches tell creatures who aren't witches that they've just returned from four days of casting spells and boiling bats?"

"Witches don't boil bats!" I said indignantly.
