Lying on the lead, in the full sun, was an old man with white hair. His face was bruised and battered, and one eye was closed, and as they saw when they got closer, his hands were tied behind him.
He heard them coining and groaned again, and tried to turn over to shield himself.
«It's all right,» said Will quietly. «We aren't going to hurt you. Did the man with the knife do this?»
«Mmm,» the old man grunted. «Let's undo the rope. He hasn't tied it very well….» It was clumsily and hastily knotted, and it fell away quickly once Will had seen how to work it. They helped the old man to get up and took him over to the shade of the parapet
«Who are you?» Will said. «We didn't think there were two people here. We thought there was only one.»
«Giacomo Paradisi,» the old man muttered through broken teeth. «I am the bearer. No one else. That young man stole it from me. There are always fools who take risks like that for the sake of the knife. But this one is desperate. He is going to kill me.»
«No, he en't,» Lyra said. «What's the bearer? What's that mean?»
«I hold the subtle knife on behalf of the Guild. Where has he gone?»
«He's downstairs,» said Will. «We came up past him. He didn't see us. He was waving it about in the air.»
'Trying to cut through. He won't succeed. When he —» «Watch out,» Lyra said.
Will turned. The young man was climbing up into the little wooden shelter. He hadn't seen them yet, but there was nowhere to hide, and as they stood up he saw the movement and whipped around to face them.
Immediately Pantalaimon became a bear and reared up on his hind legs. Only Lyra knew that he wouldn't be able to touch the other man, and certainly the other blinked and stared for a second, but Will saw that he hadn't really registered it. The man was crazy. His curly red hair was matted, his chin was flecked with spit, and the whites of his eyes showed all around the pupils.
And he had the knife, and they had no weapons at all. Will stepped up the lead, away from the old man, crouching, ready to jump or fight or leap out of the way.
The young man sprang forward and slashed at him with the knife — left, right, left, coming closer and closer, making Will back away till he was trapped in the angle where two sides of the tower met.
Lyra was scrambling toward the man from behind, with the loose rope in her hand. Will darted forward suddenly, just as he'd done to the man in his house, and with the same effect: his antagonist tumbled backward unexpectedly, falling over Lyra to crash onto the lead. It was all happening too quickly for Will to be frightened. But he did have time to see the knife fly from the man's hand and sink at once into the lead some feet away, point first, with no more resistance than if it had fallen into butter. It plunged as far as the hilt and stopped suddenly.
And the young man twisted over and reached for it at once, but Will flung himself on his back and seized his hair. He had learned to fight at school; there had been plenty of occasion for it, once the other children had sensed that there was something the matter with his mother. And he'd learned that the object of a school fight was not to gain points for style but to force your enemy to give in, which meant hurting him more than he was hurting you. He knew that you had to be willing to hurt someone else, too, and he'd found out that not many people were, when it came to it; but he knew that he was.
So this wasn't unfamiliar to him, but he hadn't fought against a nearly grown man armed with a knife before, and at all costs he must keep the man from picking it up now that he'd dropped it.
Will twisted his fingers into the young man's thick, damp hair and wrenched back as hard as he could. The man grunted and flung himself sideways, but Will hung on even tighter, and his opponent roared with pain and anger. He pushed up and then threw himself backward, crushing Will between himself and the parapet, and that was too much; all the breath left Will's body, and in the shock his hands loosened. The man pulled free.
Will dropped to his knees in the gutter, winded badly, but he couldn't stay there. He tried to stand — and in doing so, he thrust his foot through one of the drainage holes. His fingers scraped desperately on the warm lead, and for a horrible second he thought he would slide off the roof to the ground. But nothing happened. His left leg was thrust out into empty space; the rest of him was safe.
He pulled his leg back inside the parapet and scrambled to his feet. The man had reached his knife again, but he didn't have time to pull it out of the lead before Lyra leaped onto his back, scratching, kicking, biting like a wildcat. But she missed the hold on his hair that she was trying for, and he threw her off. And when he got up, he had the knife in his hand.
Lyra had fallen to one side, with Pantalaimon a wildcat now, fur raised, teeth bared, beside her. Will faced the man directly and saw him clearly for the first time. There was no doubt: he was Angelica's brother, all right, and he was vicious. All his mind was focused on Will, and the knife was in his hand.
But Will wasn't harmless either.
He'd seized the rope when Lyra dropped it, and now he wrapped it around his left hand for protection against the knife. He moved sideways between the young man and the sun, so that his antagonist had to squint and blink. Even better, the glass structure threw brilliant reflections into his eyes, and Will could see that for a moment he was almost blinded.
He leaped to the man's left, away from the knife, holding his left hand high, and kicked hard at the man's knee. He'd taken care to aim, and his foot connected well. The man went down with a loud grunt and twisted away awkwardly.
Will leaped after him, kicking again and again, kicking whatever parts he could reach, driving the man back and back toward the glass house. If he could get him to the top of the stairs…
This time the man fell more heavily, and his right hand with the knife in it came down on the lead at Will's feet. Will stamped on it at once, hard, crushing the man's fingers between the hilt and the lead, and then wrapped the rope more tightly around his hand and stamped a second time. The man yelled and let go of the knife. At once Will kicked it away, his shoe connecting with the hilt, luckily for him, and it spun across the lead and came to rest in the gutter just beside a drainage hole. The rope had come loose around his hand once more, and there seemed to be a surprising amount of blood from somewhere sprinkled on the lead and on his own shoes. The man was pulling himself up —
«Look out!» shouted Lyra, but Will was ready.
At the moment when the man was off balance, he threw himself at him, crashing as hard as he could into the man's midriff. The man fell backward into the glass, which shattered at once, and the flimsy wooden frame went too. He sprawled among the wreckage half over the stairwell, and grabbed the doorframe, but it had nothing to support it anymore, and it gave way. He fell downward, and more glass fell all around him.
And Will darted back to the gutter, and picked up the knife, and the fight was over. The young man, cut and battered, clambered up the step, and saw Will standing above him holding the knife; he stared with a sickly anger and then turned and fled.
«Ah,» said Will, sitting down. «Ah.»
Something was badly wrong, and he hadn't noticed it. He dropped the knife and hugged his left hand to himself. The tangle of rope was sodden with blood, and when he pulled it away —
«Your fingers!» Lyra breathed. «Oh, Will —»
His little finger and the finger next to it fell away with the rope.
His head swam. Blood was pulsing strongly from the stumps where his fingers had been, and his jeans and shoes were sodden already. He had to lie back and close his eyes for a moment. The pain wasn't that great, and a part of his mind registered that with a dull surprise. It was like a persistent, deep hammer thud more than the bright, sharp clarity when you cut yourself superficially.
