Marcellus dared not risk discovery yet. He needed precious time to set the Fyre going, time to prove that it was not a danger to the Castle. Although Marcia had agreed that he could start up the Fyre, Marcellus knew that she assumed that the Fyre was the small furnace in the Great Chamber of Alchemie and Physik. Indeed, that was what he had led Marcia to think. Julius Pike had told Marcellus that he would make sure that no ExtraOrdinary Wizard would ever give permission to open up the Chamber of Fyre again—and Marcellus had believed him.

And so now Marcellus turned his attention to the little brass wheels that would open heat vents scattered throughout the Castle and wick excess heat safely away from the awakening Fyre. Marcellus had given this some thought—the trick was to open vents in places where the unusual heat could be explained away as something else. He took a rumpled piece of paper from his pocket and consulted a list. Counting carefully along, he spun nine selected wheels until they stopped. Marcellus checked his paper again, checked the wheels and stood back satisfied.

By now a red pointer on a dial was telling him that the reservoir was nearly full; Marcellus turned the wheel to close the sluice gate, rechecked his list and left the control room. Job done.

Two hours later, the water was flowing through the Cauldron and the Fyre was beginning the slow, gentle process of coming alive once again. Wearily, Marcellus pushed his Alchemie Keye into the dip on the lower Fyre hatch. He remembered the time, when they were both growing old, that Julius had come to see him. He had given Marcellus back the Alchemie Keye because, “I trust you, Marcellus. I know you will not use it.” And he hadn’t.

Well, not until now.

Romilly and Partridge had long gone back to work, but in the Vaults, Beetle still watched the Live Plan—he knew that what goes down must come up. Beetle’s stomach rumbled and as if on cue, Foxy, Chief Charm Scribe, poked his head around the half-open door. Beetle looked up.

Marcellus climbed through the lower Fyre hatch. Once again, he was a blip on The Live Plan of What Lies Beneath.

“Ta-da!” said Foxy. “Sausage sandwich!” He put a neatly wrapped package beside Beetle’s candle. It smelled wonderful.

Marcellus closed the lower Fyre hatch and began to climb—fast.

“Thanks, Foxy,” said Beetle. He looked back at the plan but his eyes, tired after so much staring, did not focus well enough to see the Marcellus blip. He glanced at the sausage sandwich longingly. He had no idea he was so hungry.

“I’ll unwrap it for you,” said Foxy. “You don’t want sticky stuff on the Live Plan.”

Beetle peered at the plan once more.

“Seen something?” asked Foxy.

“Yeah—I think . . .” Beetle pointed to the Marcellus blip.

Foxy leaned forward and his beaky nose cast a shadow over the blip.

Marcellus reached the upper Fyre hatch.

“Shove over, Foxy,” said Beetle, irritated. “You’re blocking the light.”

“Oh. Sorry.”

Beetle looked up. “Sorry, Foxo. Didn’t mean to snap. Thanks for the sandwich.”

Marcellus was through the upper Fyre hatch and off the Live Plan.

Beetle bit into his sausage sandwich.

And down in the Deeps, the Fyre began to wake.

A WHITE WEDDING

The Big Freeze had come in, covering the Castle in a deep blanket of snow.

On a sunny late afternoon in the breathtakingly still air, pencil-thin columns of smoke rose from a thousand chimneys up into the sky. Along Wizard Way a crowd had gathered to watch a wedding procession walk from the Great Arch to the Palace. As the procession passed by, people from the crowd dropped in behind and followed, chattering about the young couple who had just gotten married in the Great Hall of the Wizard Tower: Simon and Lucy Heap.

Simon Heap, with his curly straw-colored hair neatly tied back in a ponytail, wore new blue robes—which, as the son of an Ordinary Wizard, he was entitled to do on his wedding day. The freshly dyed blue was bright and trimmed with traditional white wedding ribbons, which trailed behind him. Lucy Heap (née Gringe) was wearing a long, white, floaty woolen dress, which she had knitted herself and edged with pink fur. She had lovingly embroidered entwined blue and pink letters “S” and “L” across the skirt. Her mother had objected to this, saying it was bad taste, and for once in matters of taste Mrs. Gringe was probably right. But it was Lucy’s Big Day and what Lucy wanted to do, Lucy was going to do. No change there, then, her brother, Rupert, had remarked.

The wedding party progressed down Wizard Way toward the Palace, crunching through newly fallen snow. The sky was a brilliant winter blue, but a small snow cloud directly above obligingly provided a few fat snowflakes, which floated down and landed on Lucy’s beribboned long brown hair, where they settled like confetti. Lucy and Simon were laughing and talking happily to each other, Lucy twirling in the snow to show off her dress and sharing a joke with her new brothers.
