But he was only buying time, and he knew it. Once Buttle overcame his initial surprise, he could use the sword's greater mobility and expose the shield's clumsiness as a weapon. He lunged at Horace's body, and the warrior was forced to revert to his double-handed grip on the shield as Buttle drove forward, lunging and cutting, looking for an opening in Horace's defense.

In Horace's position, most warriors would have given in or run. But Horace never accepted defeat. It was one of the traits that made him the great warrior that he was.

As he parried Buttle's sword strokes, his mind worked overtime, trying to find a way to defeat the bearded man before him.

If he could remount the shield on his left arm once more and draw his dagger, he could… but he knew Buttle would never give him the time he needed for that.

He considered throwing the shield, spinning it like a huge discus at Buttle and following up with the dagger as his opponent tried to avoid it. But Buttle was fast – as fast as any adversary Horace had ever faced – and an attempt like that would definitely be last ditch.

He parried two more sword cuts and deflected a thrust. Buttle may have been fast, but he was not a particularly skillful or inventive swordsman, Horace realized. He could probably parry Buttle's strokes for some time. But he couldn't simply continue to fight defensively. One mistake on his part and the battle would be over.

They faced each other, circling slowly, sword and shield moving together. Action. Reaction.

And then, in an instant, the impasse was broken.

In his peripheral vision, Horace saw a huge figure looming over the wall at the head of one of the scaling ladders. Trobar. He towered above them for a second, saw Buttle and dropped to the walkway, a huge wooden club in his hands.

Without hesitation, he charged at the man who had tried to kill Shadow, swinging the club in huge, murderous arcs.

Buttle retreated desperately, ducking and swaying to avoid the monstrous club. Trobar shambled after him, off balance and awkward yet moving with surprising speed. The club thundered against the stone walls and wooden flooring. A twenty-centimeter piece broke off and went spinning away into the darkness below as he struck the walkway on one follow-through. Trobar grunted with the effort, his eyes fixed on the man who had hurt Shadow.

Yet courage and the desire for revenge were not going to be enough. Buttle was too fast and despite his fearsome appearance, Trobar was totally unskilled in weapons and combat. His clumsy, crushing blows with the club were a primitive, instinctive reaction to his anger. He soon tired, his strokes becoming wilder and increasingly off-target.

Horace saw Buttle's confidence growing and knew how the fight would end. He dashed desperately back to where his own sword still leaned against the wall. As his fingers closed around the familiar grip, he heard a startled cry of pain behind him. Looking back, he saw the club fall from Trobar's nerveless fingers as Buttle withdrew the sword from a thrust in the giant's side.

Trobar clutched at the sudden fierce pain, feeling his own hot blood course over his fingers. Only his massive strength kept him standing for a few seconds. He looked, uncomprehendingly, down to his side, where the sword had cut into him. This was how Shadow must have felt, he thought vaguely. He saw that Buttle was about to thrust at him again and, hopelessly, threw up his arm to ward off the sword.

The point of the blade thrust into his massive forearm, sliding through muscle and flesh, jarring off the bone. Trobar whimpered in pain once more as Buttle angrily withdrew the sword. He had aimed for the giant's heart, but Trobar's last-minute reaction had thwarted him.

This time, he thought.

But there was to be no second time. As the blade darted forward again, Horace's sword flicked it to one side. And now John Buttle learned what swordsmanship was really about.

He staggered back desperately under Horace's lightning-fast and constantly varying attack, never knowing where the next strike was going to be aimed, never knowing from which direction it might come. Horace's sword was a glittering wheel of light in the flare of the torches, a nonstop onslaught that left Buttle no time to plan his own counterattack, and barely time to defend himself.

He was holding the sword in both hands now, horrified by the crushing force behind each of Horace's single-handed strokes – seemingly delivered without the slightest effort. Every one jarred his hands, wrists and arms. He knew he could never hope to defeat this man, and so he took the only way he could think of.

He leapt back and dropped his sword, hearing it clatter on the walkway timbers.

Then he dropped to his knees, hands held out wide.

"Mercy!" he shouted hoarsely. "Please! I surrender! Mercy, I beg you!"

Horace's downstroke had already started, and his eyes flinched with the effort of stopping. Buttle saw the stroke begin and cowered, turning his face away from death. Then, as the sudden pain didn't come, he looked up, fearfully, to see Horace standing over him, a disgusted look on his face.

"You really are a gutless piece of scum, aren't you?" Horace said. He looked back to where the huge figure of Trobar had sunk to the planking, blood soaking the walkway around him. Then he looked at Buttle again, remembering all that Gundar and Will had told him. In one smooth movement, he sheathed his sword. He saw a light of hope kindle in the kneeling man's eyes, hope overlaid with a crafty, self-serving expression.

Cowards and bullies, they were all the same, thought Horace. His thoughts went back to the past again, to his confrontation with the three bullies who made his life a living hell in his first year as an apprentice.

In a sudden blind flare of rage, he grabbed Buttle by the front of his shirt and heaved him to his feet. As part of the same movement, Horace hit him with a short, savage right cross, perfectly timed, perfectly weighted, perfectly executed, with no wasted motion.

Buttle screamed as he felt his jaw dislocate. His vision went black, and his knees turned to jelly. Horace let go of his shirt front and allowed the insensible figure to crash to the planks, bouncing off the stone wall as he went. Horace shook his head, then turned and hurried back to Trobar.

The giant was alive, but he had lost a massive amount of blood. Horace rolled him over carefully. Long and bitter experience had taught him to carry a basic first-aid pack whenever he went into battle. It was in a pouch on the back of his belt, and he found a clean bandage there. He held it against the sword wound in Trobar's side, binding it in place with the giant's own belt. The bandage was instantly soaked with blood, but at least it stanched the flow.

Trobar's eyes were open, and he looked at Horace, uncomprehending. Horace forced a smile onto his face.

"You'll be fine," he said. Trobar's lips moved, and Horace shus hed him.

"Don't try to talk. Rest. Malcolm will fix you up," he said. He hoped the doubt that he felt didn't show in his eyes. The wound was a serious one, and even Malcolm's skill would be tested by it.

Trobar tried again. This time, he managed a vague croak. Horace saw the fear in the giant's eyes. And as he saw it, he realized that Trobar wasn't looking at him. He was looking behind him.

He swung around. Buttle, his face swollen and distorted, blood running down from his mouth, stood above him, his sword raised in a double-handed grip high over his head. There was hatred in his eyes. Hatred and triumph. In another second, Horace would be dead.

But there wasn't another second. Gundar Hardstriker's ax came spinning out of the night, rotating end over end with a peculiar haoomp haoomp haoomp sound.

Eight kilograms of solid wood and heavy iron, it struck Buttle in the back. He grunted in pain, his eyes glazed in surprise and shock. The sword fell to the ground behind him as he staggered under the impact. He tried feebly to reach behind him to pluck the massive weapon free, but he lacked the strength and the purpose. He took a pace to the left, lurched, reeled. And fell into the dark courtyard below them with a resounding thud.
