I nodded. “I think so. But you can’t wait for me day and night down here. What’s more, Gideon could turn up anytime. After all, he has to elapse as well.”

“I know what to do,” said Lucas, with growing enthusiasm. “If you land in this room next time, just come up to me! My office is on the second floor. You’ll only have to pass two guards, but that’s no problem if you say you’ve lost your way. You’re my cousin. My cousin Hazel from the country. I’ll start telling everyone about you this very day.”

“But Mr. Whitman says this room is always kept locked, and anyway I don’t know exactly where we are.”

“You’ll need a key, of course. And the password for the day.” Lucas looked around him. “I’ll get a key made for you and leave it somewhere here. Same with the password. I’ll write it on a note and leave it in our hiding place. Somewhere in the brickwork would be best. The bricks are coming a bit loose just there, see? Maybe we can make a hollow space behind them.” He got to his feet, made his way through the junk in the cellar, and knelt down in front of the wall. “Look, here. I’ll come back with tools and make a perfect hiding place. When you come back next, you just have to pull out this brick, and then you’ll find the key and the password.”

“But there are a lot of bricks,” I said.

“Just remember this one, fifth row from the bottom, roughly in the middle of the room. Damn, that was my fingernail! Never mind, that’s my plan, and I think it’s a good one.”

“But then you’d have to come down here every day from now on to change the password,” I said. “How are you going to fix that? Aren’t you studying at Oxford?”

“The password isn’t changed daily,” replied Lucas. “Sometimes we use the same one for weeks on end. Anyway, this is our only chance to fix another meeting. Remember that brick. I’ll draw a plan as well, so that you can find your way up. There are secret passages from here that go over half of London.” He looked at his watch. “Now, let’s sit down again and make notes. Systematically. You wait, we’ll both know more in the end.”

“Or alternatively we’ll still be two people without the faintest idea down in a musty cellar.”

Lucas put his head to one side and grinned at me. “Maybe, just in passing, you could tell me whether your grandmother’s name begins with an A or a C?”

I had to smile. “Which would you rather?”

“GWENNY! GWENNY, wake up!”

With difficulty, I struggled up from the depths of my dream. In the dream I’d been an ancient, hunchbacked old woman sitting opposite Gideon, who was looking terrific, and claiming that my name was Gwyneth Shepherd and I came from the year 2080. Now I looked into the familiar, snub-nosed face of my little sister, Caroline.

“At last!” she said. “I thought I’d never get you to wake up. I was asleep when you came in yesterday evening, though I tried so hard to stay awake. Have you brought one of those gorgeous dresses back again?”

“Not this time.” I sat up. “I was able to change when I got there.”

“Is it always going to be like this? You not coming home until I’m asleep? Mum has been so odd since this happened to you. And Nick and I miss you. Suppers don’t seem right when you’re not there.”

“They didn’t seem right before,” I reassured her, dropping back on the pillow.

A limousine had brought me back yesterday evening. I didn’t know the chauffeur, but redheaded Mr. Marley had come all the way to the front door of our house with me.

I hadn’t seen Gideon again, and just as well. It was quite enough to dream of him all night.

My grandmother’s butler, Mr. Bernard, had let me in, polite and otherwise totally impassive, as ever. My mum had come downstairs to welcome me home, hugging me as tightly as if I’d just come back from an expedition to the South Pole. I was glad to see her, too, although I was still rather cross with her. It was so odd, finding out that your own mother had been lying to you. And she still wouldn’t tell me why. Apart from a few cryptic remarks—trust no one … dangerous … secret … blah blah blah—she hadn’t told me anything to explain her behavior. So what with that and the fact that I was just about dying of exhaustion, I’d simply eaten a small piece of roast chicken and then fallen into bed without telling Mum about the day’s events. And what exactly was she going to do with the information? She worried far too much anyway. I thought she looked almost as exhausted as me.

Caroline shook my arm again. “Hey, don’t go back to sleep!”

“Okay.” I swung my feet over the edge of the bed and realized that, in spite of my long phone call to Lesley before I went to sleep, I did feel fairly well rested. But where was Xemerius? He’d disappeared when I went into the bathroom last night, and I hadn’t seen him since.

Under the shower, I finally washed my hair, using Mum’s expensive shampoo, which wasn’t really allowed, and some of her conditioner as well, even at the risk of being given away by the wonderful scent of roses and grapefruit. As I rubbed my head dry, I instinctively wondered whether Gideon liked roses and grapefruit and then called myself sternly to order.

I’d hardly had a couple of hours’ sleep, and here I was thinking of him again! And just what was so great about what had happened anyway? We’d done a bit of necking in the confessional, but right after that, he’d gone back to being his old insufferable self, and my fall from cloud nine was not something I wanted to remember, whether or not I’d had enough sleep. As I’d told Lesley when she wouldn’t drop the subject last night.

I blow-dried my hair, got dressed, and went down all the flights of stairs to the dining room. Caroline, Nick, Mum, and I lived on the third floor of our house. Unlike the rest of the place, which had been in my family’s hands since the beginning of time (or even longer), it was at least reasonably comfortable.

The rest of the house was stuffed with antique furniture and pictures of assorted ancestors, few of whom were exactly a sight for sore eyes. And we had a ballroom where I had helped Nick learn how to ride a bike—in secret, of course, but these days traffic in central London was terribly dangerous, as everyone knew.

As so often, I wished Mum and the three of us could eat up on the third floor, where we had our own rooms, but my grandmother, Lady Arista, insisted on all of us meeting at mealtimes in the gloomy dining room. Its paneling was the color of milk chocolate; at least, that was the only nice comparison I’d ever thought of. The others were less appetizing.

Today the atmosphere was distinctly better than the day before, as I noticed the moment I came into the room. Well, that was something, anyway.

Lady Arista, who always seemed rather like a ballet teacher about to rap you over the knuckles, said “good morning” in friendly tones, and Charlotte and her mother smiled at me as if they knew something and I hadn’t the faintest idea of it.

Since Aunt Glenda never normally smiled at anyone (unless you count a sort of sour lift at the corners of her mouth), and Charlotte had said some horrible things to me only yesterday, I immediately felt suspicious.

“Has something happened?” I asked.

My twelve-year-old brother Nick grinned at me as I sat down beside Caroline, and Mum pushed a huge plateful of scrambled egg on toast over to me. I almost fainted away with hunger as the delicious smell rose to my nostrils.

“Oh, my goodness,” said Aunt Glenda. “I suppose you want your daughter consuming a whole month’s supply of fat and cholesterol in a single day, do you, Grace?”

“That’s right,” said Mum, unfazed.

“She’ll hate you later for not taking better care of her figure,” said Aunt Glenda, smiling again.

“Gwyneth’s figure is faultless,” said Mum.

“For now—maybe,” said Aunt Glenda. She was still smiling.

“Did you two put something in Aunt Glenda’s tea?” I asked Caroline in a whisper.

“Someone phoned a few minutes ago, and ever since then Aunt Glenda and Charlotte have been on top of the world,” Caroline whispered back. “You’d think someone had cast a magic spell over them.”

At that moment, Xemerius landed on the windowsill outside, folded his wings, and came in through the glass of the windowpane.

“Good morning,” I said cheerfully.

“Good morning,” replied Xemerius, hopping down from the windowsill and up on an empty chair.

While the others looked at me, rather surprised, Xemerius scratched his belly. “Yours is rather a large family. I haven’t quite managed to get the hang of it yet, but I did notice there are a lot of women about the place. Too many, if you ask me. And most of the time, half of them look like they need a good tickling.” He shook out his wings. “Where are the fathers of all these children? And where are the pets? A great big house like this, and not so much as a canary! I’m disappointed.”

I grinned. “Where’s Great-aunt Maddy?” I asked as I happily began to eat.

“I am afraid my dear sister-in-law’s need for sleep is greater than her curiosity,” said Lady Arista, with dignity. She was sitting ramrod straight at the breakfast table, eating half a slice of buttered toast with her fingers delicately spread. (I’d hardly ever seen her anything but ramrod straight.) “Getting up so early yesterday left her in a bad temper all day long. I don’t think we’ll see her before ten this morning.”

“Glad to hear it,” said Aunt Glenda. “All that talk of sapphire eggs and clocks on towers really gets on my nerves. Well, how are you feeling, Gwyneth? I imagine this must all be very confusing for you.”

“Hm,” I murmured.

“It must be so dreadful, finding out all of a sudden that you’re born to higher things when you can’t live up to expectations.” Aunt Glenda forked up a small piece of tomato from her plate.

“Mr. George says Gwyneth has acquitted herself very well so far,” said Lady Arista, although before I could feel cheered by this evidence of solidarity she added, “In the circumstances, anyway. Gwyneth, you’ll be fetched from school again today and taken to the Temple. This time Charlotte will go with you.” She sipped her tea.

I couldn’t open my mouth without letting scrambled egg drop out, so I just gawped at her in alarm, while Nick and Caroline spoke for me. “Why?”

“Because,” said Aunt Glenda, wagging her head in a peculiar way, “because Charlotte knows all the things that Gwyneth ought to know if she’s to do any kind of justice to her task. So on account of the chaotic events of the last few days—and as I’m sure we can all imagine only too vividly, they must indeed have been chaotic—the Guardians want Charlotte to help her cousin prepare for the rest of her time traveling.” She looked as if her daughter had just won an Olympic gold medal. At the very least.

The rest of my time traveling? What was this all about?

“Who’s that skinny, redheaded battle-ax with the sharp tongue?” inquired Xemerius. “I hope for your sake she’s only a distant relation.”
