It was possible that Lord Sunday might not even want the other Keys. Arthur had no idea what Sunday really wanted. After all, it was Saturday who had set the fall of the House in motion, and Saturday who had invaded the Incomparable Gardens, because the Gardens were the only part of the House likely to survive the onrush of Nothing that had already taken the Far Reaches, the Lower House and who knew what else by now.

All Arthur knew was that Lord Sunday was one of the original faithless Trustees who had not obeyed the Architect, and had broken and hidden the seven Parts of the Will instead of following the Will’s instructions. As Arthur was effectively an agent of the Will, and the supposed Rightful Heir of the Architect, Lord Sunday was automatically his enemy.

But maybe we can work something out, he thought. We both have to stop the tide of Nothing, to save the House and the rest of the Universe. Maybe I could confirm that he would stay in charge of the Incomparable Gardens and he’d be left alone, that seems to be what he wants…

Arthur sighed as his thoughts continued into less optimistic regions.

Who am I kidding? Dame Primus would never agree. Besides, who knows what Sunday is really up to? I have to escape! But how?

He sighed again, the sigh turning into a grimace of pain as the dragonfly changed direction again, swinging Arthur out wide, scraping the manacles across the raw wounds on his wrists, no matter how tightly he held the chain above the manacles.

With the pain came an unexpected realisation. Since he’d taken the Fifth Key at least, any pain he felt had come with a burning desire to retaliate, to strike against whoever or whatever had caused him hurt. But he was not angry now and he felt no great store of rage waiting to explode within him.

I am weaker without my Keys, thought Arthur. But I am also more myself.

They were heading towards a new landmark, a tall green hill that was still several miles away. It looked a lot like Doorstop Hill in the Lower House, though it was significantly higher and the bottom slopes were terraced and dotted with trees. There was also something on the crest of the hill, a low building or construction of some kind, but it was too far for him to easily identify.

Directly below him, the variety of gardens continued, still divided and penned in by the tall green hedges. Arthur watched them flicker by as he desperately tried to think of some stratagem to gain his release. He let his eyes go out of focus, half-lidding them against the rushing wind, and the gardens below blurred into a patchwork of many shades of green and brown and blue.

Blue, thought Arthur.

He blinked and refocused. There was a lake and, about half a mile beyond, one of those strange, truncated oceans dumping its waves on to a two-hundred-yard-long stretch of cut-off beach.

Navigable waters, thought Arthur, swiftly followed by a single, piercing image of a tall, white-bearded sailor with deep-set eyes of the clearest blue, wielding a harpoon that glittered and shone with the most powerful sorcery.

This was the Mariner, second son of the Architect and the Old One, who had sworn to aid Arthur three times and had already done so twice. Wherever there were navigable waters, the Mariner could sail, and Arthur thought that if anything other than the Seventh Key could break his chains, it would be the Mariner’s harpoon.

I have to call him straightaway, since he could take ages to get here. Which means I need my medal.

The Mariner’s medal was in Arthur’s belt pouch, near his hip, which presented a problem. Suspended as he was, with his wrists manacled together, he couldn’t just reach down, undo the pouch and retrieve it. Nor, after a few attempts, could he pull himself up high enough to get his hands near the pouch, because when he did so he started to spin around violently.

Next, Arthur tried swinging his legs up so that he could hang upside down. But a few attempts showed him that even though he could manage to turn upside down and get his hands near his belt pouch without going into the same sort of spin, there was no way he could undo the pouch and get the medallion out, at least not without a very high chance of the medallion and his yellow elephant simply dropping out and being lost forever.

He was still trying to work out how he could get the medal when the dragonfly began to descend. It was still flying towards the terraced hill Arthur had seen, only it was no longer aiming for the top of the hill, but at a point about halfway up.

Arthur swung himself right way up again as he got lower, and tried to stop his spin. There was something on the terrace that had caught his eye and he wanted a better look.

He got it, and he felt a chill colder than the icy steel. On the terrace halfway up the hill, lying flat, was a twenty-foot-wide clock face, with vertical numbers of blue sorcerous metal. The clock had long, sharply pointed hands, and next to their central pivot was a small trapdoor.

It was a smaller replica of the Old One’s prison, save that there was no one chained to the clock hands.

Or at least, Arthur thought, there was no one chained there yet…

CHAPTER NINE

The elevator fell faster than was usual, and the ride was far less smooth. Suzy and Giac were thrown against the walls, and Part Six of the Will had to constantly flap its wings to keep its balance, finally just latching on to Suzy’s shoulder. It continued to flap there too, as Suzy tried to wedge herself into one corner to keep steady, with Giac in the opposite corner.

Even more alarming, every now and then a tiny globule of Nothing would explode through the floor and exit through the ceiling. This mostly happened near the back of the elevator and the three passengers kept well away. If the Nothing actually hit anyone, it would dissolve everything in its upward path. Even a glancing pass might destroy a hand or foot.

It was also a frightening indication that Nothing was continuing to impinge on the House. If there were globules and particles of Nothing loose in the elevator shafts, it was likely the Void had breached more defences.

“Are you sure you pressed the right button?” asked Suzy. “Cos you know half the House is just Nothing now, and if we’re dropping into it—”

“The corroded buttons indicate high contamination by Nothing,” said the Will, who had been studying the rows of bronze or formerly bronze buttons. “Those that are entirely black and crumbled show lost portions of the House.”

“So the one for the Great Maze was still bright?” asked Suzy. “That’s good.”

“Not entirely,” said the Will. “There are several elevator positions within the Maze. Some of them are black. The one I chose is a little tarnished, and the verdigris is spreading, even in this short time.”

“The Maze is dissolving?” asked Suzy. “Nothing is spreading there as well?”

“It appears so,” said the Will. “I think we had better hurry this elevator up.”

It flew from Suzy’s shoulder, up to the ceiling above the buttons and, using its beak like an ice pick, smashed through a small walnut-and-ivory veneered panel that was set into the plainer wood. There was a gold ring behind the panel.

The Will glanced back down and said, “Crouch and brace yourselves.”

Suzy and Giac obeyed. The raven grabbed the ring, folded its wings and dropped back down to Suzy’s shoulder, pulling a slender golden chain out of the ceiling by the ring. As the chain grew longer, the elevator’s speed increased. By the time the Will arrived on Suzy’s shoulder, she felt herself rising into the air, suddenly weightless as the elevator accelerated down.

“I’m floating!” she cried. “This is great!”

“Is it?” asked Giac worriedly. “Are you sure?”

“Hold on!” warned the Will. “We’ll slow down just as fast. Or hit very hard. One, two, three, four, five, six—”

The raven released the ring on “six” and the chain shot back into the ceiling. As it did so, the elevator slowed suddenly, slamming Suzy and Giac to the floor. A few seconds later, there was a terrible impact. The elevator exploded around them, throwing them into the air again in a storm of splinters and broken floorboards. Before they could fall back down, everything tilted over on a sharp incline and all three of them slid down the wall and ended up in a confused tangle in the dangerous corner where the Nothing globules had turned the elevator into a sieve.

Finally a bell went ping and the inner door slid open to reveal a bent and buckled grille door that was hanging off its hinges. Beyond it lay a guardroom, where a dozen somewhat surprised Denizens uniformed in the buff coats and grey trousers of the Moderately Honourable Artillery Company were snatching up and readying their musketoons, pistols, sparkizan halberds and swords.

“Guess we’re here,” said Suzy as she crawled across Giac’s legs and brushed the Will’s wings away from her face, since it was perched on her head. “Wherever here is.”

She stood up, brushed off the splinters and dust, and held up her hands, which seemed a wise precaution given the number of Nothing-powder weapons that were now aimed at her, including a small, wheeled artillery piece that was being pushed over by another half dozen artillerists, its bronze barrel coming into alignment with the door of the elevator.

“I’m General Suzy Turquoise Blue, personal aide-de-camp to Lord Arthur,” she called out. “Who’s in command here?”

The weapons were not lowered and no one answered.

Suzy had a moment of doubt, which was unusual for her, as she wondered whether the artillerists had gone from being moderately honourable to dishonourable, joining the Piper or Saturday. Then a Gun-Sergeant, his sleeves resplendent with gold stripes and crossed cannons, gestured to the other Denizens, who lowered their weapons a little, though not so much that anyone in the elevator would have a chance to break out. The gunner with the slow match near the cannon also lifted this burning fuse away from the touchhole, but not enough for anyone to get comfortable.

“Stay there, ma’am, and you others,” the Gun-Sergeant called out. “Marshal Dusk commands here and we are under orders to take no chances. I saw you at the Citadel fight, ma’am, but seeing ain’t always believing, so if you’ve no objection, we’ll send word to the Marshal.”

He made a sign with his hand and one of the artillerists towards the rear slid out around the heavy ironbound door on the opposite side from the elevator.

“Good idea,” said Suzy. “Um, where is here? We’re not at the Citadel?”

“This here’s the Cannon Arsenal,” said the Gun-Sergeant. He was about to add something else when he was interrupted by three distant horn blasts from somewhere outside.

“You might want to block your ears,” said the Gun-Sergeant, though neither he nor any of the other gunners made any move to do so.

Giac promptly obeyed, and the Will thrust its head under its wing. Suzy however was about to ask why when there was a sudden titanic blast outside. The stone walls of the guardroom shook and the elevator canted over even more, till it was almost horizontal, and Suzy was sitting on what used to be the wall.

The Gun-Sergeant said something, but Suzy couldn’t hear it over the ringing in her ears. As the tinnitus subsided the Gun-Sergeant spoke again, and though Suzy couldn’t really hear it she could work out what he was saying by watching his lips.

“Told you so,” he said.

Suzy grinned and mimed cleaning her ears out with her fingers. It actually helped, so she kept at it and looked in surprise at her blackened fingertips. “Must be quite a while since the Bathroom Attendants washed between my ears,” she said proudly. “I don’t reckon they’ll get another chance.”

“I think it very unlikely,” said Part Six of the Will. It hopped on to Suzy’s shoulder and peered at the artillerists. “Tell me, Sergeant, why are you all wearing black armbands? And what was that explosion?”

The Gun-Sergeant narrowed his eyes. “I’m not answering questions from a bird of dubious background,” he said. “You look like some kind of Nithling.”

“I beg your pardon,” said the Will. “I’ll have you know that I am Part—”

“Shush,” said Suzy, clasping the raven’s beak shut. “The bird’s all right. Marshal Dusk will vouch for it, as well as for me.”

“What about him?” asked one of the other gunners, pointing at Giac. “He’s one of Saturday’s, isn’t he?”

“Well, he was,” said Suzy. “Only now ’e’s not, orright? He works for Lord Arthur, same as the rest of us.”

“If you say so,” sniffed the gunner, but he maintained a ready stance with his sparkizan, and kept a thin blue spark sidling along the blade of the halberd-like weapon.

“So why the black armbands, then?” asked Suzy, repeating the Will’s question. “And what was that boom? Someone smoking in the Nothing-powder store again?”

A chorus of irritated voices answered the last question first. It was a commonly held belief in the rest of the Army that the Moderately Honourable Artillery Company’s artillerists and engineers were always on the verge of blowing themselves up by accident and that only good luck spared them. It was a completely unfounded belief, but that didn’t make it any less irritating.

“Quiet!” roared the Gun-Sergeant. The ruckus died down, and the burly Denizen turned back to Suzy. “Now General, presuming you is who you say you are, you know that there ain’t no artillerist who smokes, even if we could get the makings, which we can’t since the fall of the Far Reaches. Likewise we don’t play games with matches or fire-starters or flame-sprays or sparkizans or any of the things that them other units says we do. So we don’t take kindly to jokes about our Nothing-powder stores blowing up or—”

He paused suddenly, and with the sixth sense of a long-serving sergeant, suddenly braced to attention and shouted, “Stand fast!”
