But still he kept holding the mirror up above his head, even as he fell to his knees. He used the pain, channelling it to fuel his concentration, directing his will against the rush of Nothing.
Finally, it was too much. Arthur could neither bear the pain nor continue the effort. He fell forward on his face, his screams becoming dull sobs. His strength used up, he dropped the Fifth Key on the narrow band of grass that was all that remained of the lawns that had once surrounded the Dayroom villa.
He lay there, partially stunned, awaiting annihilation, knowing that he had failed and that when he died, the rest of the Universe would follow. All he loved would be destroyed, back on Earth, in the House, and in the worlds beyond.
A minute passed, and then another, and the annihilation didn’t happen. As the pain in his bones ebbed, Arthur groaned and rolled over. He would face the Nothing, rather than be snuffed out by it while he lay defeated upon the grass.
The first thing he saw was not incipient destruction but a delicate tracery of glowing golden lines, like a web or a mesh net of light thrown against the sky. It was holding back the great mass of threatening darkness, but Arthur could feel the pressure of the Nothing, could feel the infinite Void pushing against his restraints. He knew that it would soon overcome his net of light and once again advance.
Arthur picked up the mirror and staggered to his feet. The ground felt further away than normal, and he lost his balance for a moment, swaying on the spot. The sensation passed as he shook his head, and he ran back to the open doors. There was a telephone in the library, he knew, and he needed to call and find out where in the House was safe, instead of going somewhere that might have already succumbed to Nothing. He didn’t want to think about what would happen if he used the Fifth Key to take him straight into the Void, though it probably would have the advantage of being quick...
Or maybe the Key would protect me for a little while, Arthur thought with sudden nausea. Long enough to feel the Nothing dissolve my flesh...
He hurried along the main corridor until he saw a door he recognised. Darting through it, he leapt up the steps four at a time, bouncing off the walls as he tried to take the turns in the staircase too fast.
At the top, he sprinted down another long corridor, this one also narrowed by piles of records, many of them written on papyrus or cured hides instead of paper. Pausing to shift a six-foot-high stone tablet that had fallen and blocked the way, Arthur didn’t bother with the handle of the door at the end but kicked it open and stumbled into the library beyond.
The room was empty, and not just of Denizens. The books were gone from the shelves, as were the comfortable leather armchairs and the carpet. Even the scarlet bell rope that Sneezer had pulled to reveal the heptagonal room that housed the grandfather clocks of the Seven Dials was missing, though the room was presumably still there, behind the bookcase.
The telephone that had stood on a side table was also missing.
Arthur’s shoulders slumped. He could feel the pressure outside, like a sinus pain across his forehead. He knew it was the weight of Nothing striving to break the bonds he had placed upon it. The weight was there in his mind, making him weary, almost too weary to think straight.
‘Telephone,’ mumbled Arthur, holding out his right hand, while he cradled the Fifth Key in his left. ‘I need a telephone, please. Now.’
Without further ado, a telephone appeared in his hand. Arthur set it down on the floor and sat next to it, lifting the earpiece and bending to speak into the receiver. He could hear crackling and buzzing, and in the distance someone was singing something that sounded rather like Raindrops Keep Falling on My Head, but the words were ‘Line-drops are lining up tonight.’
‘Hello, it’s Lord Arthur. I need to speak to Dame Primus. Or Sneezer. Or anyone, really.’
The singing abruptly stopped, replaced by a thin, soft voice that sounded like paper rustling.
‘Ah, where are you calling from? This line doesn’t appear to be technically, um, attached to anything.’
‘The Lower House,’ said Arthur. ‘Please, I think I’m about to be engulfed by Nothing and I need to work out where to go.’
‘Easier said than done,’ replied the voice. ‘Have you ever tried connecting a nonexistent line to a switchboard that isn’t there anymore?’
‘No,’ said Arthur. Somewhere outside he heard a twanging sound, like a guitar string snapping. He felt it too, a sudden lurch in his stomach. His net, his defence against the Void, was breaking. ‘Please hurry!’
‘I can get Doctor Scamandros – will he do?’ asked the operator. ‘You wanted him before, it says here-’
‘Where is he?’ gabbled Arthur.
‘The Deep Coal Cellar, which is kind of odd,’ said the operator. ‘Since nothing else in the Lower House is still connected... but metaphysical diversion was never my strong suit. Shall I put you through? Hello... hello... are you there, Lord Arthur?’
Arthur dropped the phone and stood up, not waiting to hear more. He raised the mirror that was the Fifth Key and concentrated upon it, desiring to see out of the reflective surface of a pool of water in the Deep Coal Cellar – if there was such a pool of water, and a source of light.
He was distracted for an instant by the sight of his own face, which was both familiar and strange. Familiar, because it was in essence much the same as it had been at any other time he’d looked in a mirror, and strange because there were numerous small changes. His cheekbones had become a little more pronounced, the shape of his head was a bit different, his ears had got smaller...
‘The Deep Coal Cellar!’ snapped Arthur at the mirror, both to distract himself and get on with his urgent task: finding somewhere to escape to before Nothing destroyed Monday’s Dayroom.
His image wavered and was replaced by a badly lit scene that showed an oil lamp perched on a very thick, leather-bound book the size of several house bricks, which was set atop a somewhat collapsed pyramid made from small pieces of coal. The lamplight was dim, but Arthur could perceive someone on the far side of the pyramid who was raising a fishing pole over his head, ready to cast. Arthur saw only the caster’s hands and two mustard-yellow cuffs, which he immediately recognised.
‘Fifth Key,’ Arthur commanded, ‘take me to the Deep Coal Cellar, next to Doctor Scamandros.’
As before, a door of pure white light appeared. As Arthur stepped through it, he felt his defensive net tear asunder behind him and the onrush of the great wave of Nothing.
A scant few seconds after his escape, the last surviving remnants of the Lower House ceased to exist.
FOUR
ARTHUR APPEARED NEXT to a pyramid of coal, stepping out of the air and frightening the life out of a short, bald Denizen in a yellow greatcoat, who dropped his fishing pole, jumped back, and pulled a smoking bronze ball that looked like a medieval hand grenade out of one of his voluminous pockets.
‘Doctor Scamandros!’ exclaimed Arthur. ‘It’s me!’
‘Lord Arthur!’
The tattooed trumpets on Dr Scamandros’s forehead blew apart into clouds of confetti. He tried to pinch out the fuse on the smoking ball, but a flame ran around his fingers and continued on its way. Even more smoke boiled out of the infernal device.
‘Scamand-’ Arthur started to say, but Scamandros interrupted him, lobbing the ball behind a particularly large pyramid of coal some thirty feet distant.
‘One moment, Lord Arthur.’
There was a deafening crack and a fierce rush of air, closely followed by a great gout of smoke and coaldust that spiralled up into the air. Moments later, a hail of coal came down, some fist-sized pieces striking the ground uncomfortably close to the sorcerer and the boy.
