It shivered as it came under tension and began to move downwards. Having grasped it, Will dared not let go, and so he was pulled to his knees then dragged down off the beam. For a moment he swung out wide over the drop, all his weight held on one twisted forearm. His legs dangled and his gutsfilled with a paralysing terror that snatched away all power over his body.
Don’t look down, he told himself in a silent scream. Keep your head up and hang on!
Distant grinding noises rose up from the space below when the chains jerked into motion. Will felt terror engulf him. His breath came in short gasps. The imperative to keep his grip consumed him as the pain in his wrist peaked. The struggle locked his muscles in a death-like cramp. He cried out, thrashed, managed to turn himself, then captured the link gratefully between his thighs. He squeezed his chest against the link and knew that he had bought enough time until the pain subsided and he could regain his courage. It had not been elegant, but he had avoided the fall.
Of course! he thought as he clung on. It’s the vane! These chains are how they work the mechanism. They must be sending out a message.
He forced himself to recall what was up above. On the very top of the Spire the great vane would be swinging and dancing this way and that, its various parts clacking and clanging as it sent the news of an unthinkable defilement to every chapter house in Trinovant.
‘What’s the matter?’ Chlu shouted in delight. ‘Are you finding it hard to get close to me?’
Will hung on, both in body and mind. He was shaking with shock, but the pain was ebbing and it was clear from the fingers he could still flex that his wrist had not been broken. Cramp complained in every muscle, sweat streamed down his back. It was hot up here, and he realized how much closer he must have come to the sun by now, way up in the middle airs of the sky, where Gwydion said the air lost its virtue and a man’s breathing came hard.
He calmed himself, then he began to think out his bestchance. He could fit his foot into the eye at the end of the link and so let one of his legs bear his weight. The chains were within reach of one another and as one stopped moving down another began moving up. So he jammed his other foot into a link on the next chain, which fortunately soon jolted into motion. When that chain stopped, he moved on to a third, which disappointed him by going down again. But still it was clear how he might be carried up and up by making correct guesses. With luck he might get as far as the platform with its six holes.
He clambered from chain to chain, feeling for advantage, but as his mind opened he felt Chlu’s malice interfering with his judgment, willing him to fall. He overshot and saw with horror that just one more upward movement of the chain would carry him up through one of the holes. He would be stripped off the chain like a beetle from a corn stalk.
Fortunately, the next movement took him lower, but his relief lasted only a moment because now he came level with Chlu.
Having kicked away the ladder and guard rail to fling down on Will’s head, Chlu had trapped himself on a narrow ledge. Had they chosen to touch hands they could have done so, but Will’s twin crouched against the wall in that hot, dark space. He snarled, repelled by a consuming hatred, and struggled with something that protruded from the wall.
Will could see no way down, but then Chlu’s hunched shoulder moved, a catch gave way and a bar of brightness pierced the gloom as Chlu threw open a heavy wooden shutter and let in a flood of sunlight. Will saw with amazement that the builders of the Spire had seen fit to place a hatch here.
The grumbling sounds that issued from the chain holes were now complemented by the squeaking and squealingof iron joints. For a moment, Chlu’s body blocked the light, but then he climbed through the hole and once more Will was left alone.
The square of blue sky beckoned urgently.
