The note stopped everything. In the case of the Piper’s children, they literally stopped, frozen in mid-action. All of them save Arthur, who looked at Fineold with his savage-sword half out of its scabbard and Jazebeth’s hand stopped with her fingers pulling back the lock of her musketoon.
Suzy was a statue on the brink of the ramp, a small snap-hance pistol in each hand, pointed down the right-hand side of the ramp. Quicksilver was just as still across from her, her bow dropped in favour of a triangular-bladed poniard.
The New Nithlings were not frozen, but they had stopped their charge and their climbing. Those on either side of the twelve-Nithling-wide ramp assault force were turning around and withdrawing, and the rest were moving apart to create an avenue of clear space up the middle.
The tall commander was striding up that avenue, holding a simple wooden pipe to lips that were invisible behind a metal mask of dull steel, playing that one impossibly pure, impossibly sustained note.
Arthur heard movement behind him and twisted around. Sir Thursday was there, his face red and screwed up in rage.
‘Traitors!’ he screamed. ‘Five minutes is all I asked!’
Before Arthur could do anything, Sir Thursday’s sword sliced through the air and connected with the frozen Private Fineold at Arthur’s side, cutting off his head with a single stroke. Then Sir Thursday rolled his wrists and, without stopping, swung the blade back again, straight at Corporal Jazebeth.
Without thinking, Arthur parried the blow. He got his savage-sword in the way, but it was as if the gravity-condensed steel were a mere twig. Sir Thursday’s sword snapped it in half, the impact making the broken sword fly from Arthur’s hand. Sir Thursday’s blow was hardly slowed, continuing to thunk horribly into Jazebeth’s neck.
Arthur half-fell and half-jumped back as Sir Thursday swung at him, changing the blow in midair from a cut to a thrust, flicking the point at Arthur. But the Denizen didn’t follow through. Instead he leaped to the right and began to draw steps with the blade, beginning to enter the Improbable Stair.
Arthur’s stomach muscles burned as he flipped himself fully upright. He took one swift glance around. The Nithling commander was twenty feet away, slowly walking up the ramp between the Nithlings, still playing that unearthly pipe.
Sir Thursday had one foot on his glowing step, his back to Arthur.
Arthur grimaced and reached alongside his cuirass under the armhole, feeling for the emergency dagger. But his fingers closed on a small plastic box. He had it out and in his hand before he remembered what it was.
I’m going to die, he thought. But I can save my family.
He threw the box at the spike and threw himself on Sir Thursday’s back just as the Trustee disappeared into the Improbable Stair.
Twenty-five
ARTHUR GOT HIS legs wrapped around Sir Thursday’s waist and his arms around his neck as he took his first step on the treacherous marble of the Improbable Stair itself. ‘Don’t try anything!’ warned Arthur. ‘If you do anything but move on the stair, I’ll throw both of us off!’
Sir Thursday growled something, a sound so inarticulate and full of anger it might have been a beast’s noise. But he kept plodding up the stair, carrying Arthur’s weight as if the boy were no more than a light rucksack.
After twenty steps, the Trustee spoke again.
‘You’ll die for this. Mutiny is mutiny, no matter who commits it. You have sealed your own end, Lieutenant.’
Arthur did not reply. He kept all his attention on Sir Thursday’s movements, not his speech. The Trustee had his sword in his hand, and he could easily angle it back and slide it into Arthur without warning. Arthur knew he had to be ready to throw all his weight to one side, even if it ended up being a dead weight. At least Thursday would be thrown off the Stair, hopefully to somewhere horrible where it would not be easy to get back on again.
Justice will be served, said a voice in Arthur’s head. The quiet, telepathic voice of the imprisoned Part Four of the Will. I nearly had him back there. You must make him angry again.
Make him angry? Arthur thought back. Are you as crazy as he is? I don’t want to make him angry. I don’t know how I’m going to survive as it is.
It is the only form of distraction that will work on Sir Thursday, replied the Will. Distract him, and I will free myself and deliver the Fourth Key to you, Lord Arthur. Then he may be brought to justice.
I’m not making him angry here, Arthur thought back at the Will.
He considered where the least worst place would be to make Sir Thursday angry for a moment. Then he spoke aloud.
‘There must be a big briefing room at the Citadel. For the Marshals and so on, to keep up with what’s going on. Particularly with the siege happening.’
