I scrabbled away from the downed Prince, chasing my sword. Steve stood close by, laughing. With an effort, Gannen regained control and set about securing victory. Hurrying over to me, he stood on my sword so that I couldn't lift it, sheathed his own blade and grabbed my head with his good left hand. "Hurry!" he barked at Steve. "Kill him quick!"

"What's the rush?" Steve muttered.

"If Vancha dies of the wound I gave him, we'll have broken the rules of Mr Tiny's prophecy!" Gannen shouted.

Steve pulled a face. "Bloody prophecies," he grumbled. "Maybe I'll let him die and see what happens. Maybe I don't care about Tiny or…" He stopped and rolled his eyes. "Oh, how silly we are! The answer's obvious – I'll kill Vancha before he dies of your wound. That way we'll fulfil the requirements of the stupid prophecy and I'll get to hang on to Darren, so I can torture him later."

"Clever boy," I heard Mr Tiny murmur.

"Have it any way you wish!" Gannen roared. "But if you're going to kill him, kill him now, so that-"

"No!" someone screamed. Before anyone could react, a large shape shot out of the underpass beneath the bridge and hurled itself at Gannen, knocking him off me, almost toppling him into the river. Sitting up, I got a shocked fix on my most unlikely of rescuers – R. V.!

"Not gonna let you do it, man!" R.V. screamed, pounding Gannen Harst with his hooks. "You're evil!"

Gannen had been taken completely unawares, but he swiftly recovered, fumbled his sword free of its scabbard, and dug at R.V. with it. R.V. caught the sword with his gold right-handed hooks and smashed it against the ground, snapping it in two. With a roar of triumph, he slammed his silver left-handed hook into the side of Gannen's head. There was a crack and Gannen's eyes went blank. He slumped beneath R.V., unconscious. R.V. howled with joy, then drew both arms back to bring them down sharply and finish Gannen off.

Before R.V. could strike, Steve stepped up behind him and forced a knife up beneath his bushy beard, deep into his throat. R.V. shuddered and bowled Steve over. R.V. stood, spinning crazily, grabbing for the handle of the knife with his hooks. After missing it several times, he fell down, landing on his knees, head thrown back.

R.V. knelt there a moment, swaying sickeningly. Then his arms slowly rose. He gazed at the gold and silver hooks, his face glowing with wonder. "My hands," he said softly, and although his voice was gurgly with blood, his words were clear. "I can see them. My hands. They're back. Everything's OK now. I'm normal again, man." Then his arms dropped, his smile and pale red eyes froze in place, and his soul passed quietly on to the next world.

I gazed at R.V.'s peaceful expression as he knelt in his death pose. He'd left his pain behind at last, for ever. I was glad for him. If he'd lived, he'd have had to carry around the memory of the evil he'd committed while in league with the vampaneze. Maybe he was better off this way.

"And now there's two – just me and you," Steve trilled, breaking my train of thought. I glanced up and saw him standing a few metres away from R.V., smiling. Gannen Harst was still out for the count, and although Vancha was alive, he was lying motionless, wheezing fitfully, unable to defend himself or attack.

"Yes," I agreed, standing and picking up my sword. My left hand wouldn't work and my system was maybe a minute or two away from complete shutdown. But I'd enough strength left for one last fight. First though – Vancha. I paused over him and studied at his wound. It was seeping blood and his face was creased with pain. He tried to speak but words wouldn't form.

As I hovered uncertainly by the side of my fellow Prince, unwilling to leave him like this, Evanna crossed to his side, knelt and examined him. Her eyes were grave when she looked up. "It is not fatal," she said softly. "He will live."

"Thank you," I muttered.

"Save your thanks," Mr Tiny said. He was standing directly behind me. "She didn't tell you to cheer you up, silly boy. It was a warning. Vancha won't die for the time being, but he's out of the fight. You're alone. The final hunter. Unless you turn tail and run, it's down to you and Steve now. If Steve doesn't die, death will come within the next few minutes for you!"

I looked over my shoulder at the small man in the yellow suit and green Wellington boots. His face was bright with bloodthirsty glee. "If death comes," I said shortly, "it will be a far more welcome companion than you."

Mr Tiny chuckled, then stepped away to my left. Rising, Evanna took up position on my right. Both waited for me to move, so that they could follow. I spared Vancha one final glance – he grinned painfully at me and winked – then faced Steve.

He backed away from me casually, entering the shadows beneath the bridge. I trailed after him, sword by my side, taking deep breaths, clearing my mind, focusing on the death-struggle to come. Although this could have been Vancha's battle, a part of me had known all along that it would come down to this. Steve and I were opposite sides of a coin, linked since childhood, first by friendship, then hatred. It was only fitting that the final confrontation should fall to the two of us.

I entered the cool darkness of the underpass. It took my eyes a few seconds to adjust. When they did, I saw Steve waiting, right eye twitching nervously. The river gurgled softly beside us, the only noise except for our panting and chattering teeth.

"There is where we settle matters, once and for all, in the dark," Steve said.

"As good a place as any," I replied.

Steve raised his left palm. I could vaguely make out the shape of the pink cross he'd carved into his flesh eighteen years before. "Remember when I did this?" he asked. "That night, I swore I'd kill you and Creepy Crepsley."

"You're halfway there," I noted dryly. "You must be delighted."

"Not really," he said. "To be honest, I miss old Creepy. The world's not the same without him. I'll miss you even more. You've been the driving force behind everything I've done since I was a child. Without you, I'm not sure I'll have much of an interest in life. If possible, I'd let you go. I enjoy our games – the hunt, the traps, the fights. I'd happily keep doing it, over and over, a new twist here, a fresh shock there."

"But life doesn't work like that," I said. "Everything has to end."

"Yes," Steve said sadly. "That's one thing I can't change." His mood passed and he regarded me with a sneer. "Here's where you end, Darren Shan. This is your grand finale. Have you made your peace with the vampire gods?"

"I'll do that later," I snarled, and swung my sword wide, moving forward so that on its return arc he'd be within range. But before it had completed its first arc, the tip of the sword smashed into the wall. It bounced off in a shower of sparks and a shock ran down my arm.

"Silly boy," Steve purred, mimicking Mr Tiny. He raised a knife. "No room here for swords."

Steve leapt forward and jabbed the knife at me. I pulled back and lobbed my sword at him, momentarily halting him. In that second, I drew one of the knives I'd brought from Annie's kitchen. When Steve advanced, I was ready. I caught his thrust with the hilt of my knife and turned his blade aside.

There was no room in the underpass to circle one another, so we had to jab and stab, ducking and weaving to avoid each other's blows. The conditions actually played into my favour – in the open I'd have had to be nimbler on my feet, spinning to keep up with Steve. That would have exhausted me. Here, since we were so cramped, I could stand still and direct my rapidly dwindling strength into my knife hand.
