Even before the echoes of the report of my third shot faded, the air outside the stadium filled with answering gunfire, as Alice and her band of vampirites opened fire on the police standing guard. She'd summoned the homeless people before Vancha and I entered the tunnel, and positioned them around the barrier outside the stadium. After years of surviving on the scraps other people threw away, this was their time to rise. They had only a small amount of training and basic weapons, but they had passion and anger on their side, and the desire to prove themselves. So now, at my signal, they leapt the barriers around the stadium and attacked as a unified force, throwing themselves upon the startled police, sacrificing themselves where necessary, fighting and dying not just for their own lives, but for the lives of those who considered them trash.

We weren't sure of the intentions of the police. Steve might have told them to remain outside regardless of what happened within, in which case the attack by the vampirites would serve no purpose at all. But if they were there to support the vampaneze and vampets, to come to their aid if summoned, the vampirites could divert them and buy those of us inside the stadium a bit more space and time.

Most of the vampaneze guarding Steve moved to stop Vancha when he charged, but two lunged at me as I fired the pistol. They tackled me to the ground, knocking the gun from my hand. I struck out at them but they simply lay on top of me, pinning me down. They would have held me there, helpless, while their colleagues dealt with Vancha. Except…

The stars and crew of the Cirque Du Freak had also rallied to my signal. At the same time that the vampirites attacked the police, the prisoners inside the stadium turned on the vampets holding them captive. They attacked with their bare hands, driving the vampets back by sheer force of numbers. The vampets fired into the crowd and hacked wildly with their swords and axes. Several people fell, dead or wounded. But the group pushed on regardless, screaming, punching, kicking, biting – no force on Earth could hold them back.

While the bulk of the Cirque Du Freak troupe grappled with the vampets, Harkat led a small band towards the gallows. He'd grabbed an axe from a dead vampet and with one smooth swing he cut down a vampaneze who tried to intercept them, rushing past without breaking his stride.

Vancha was still locked in a struggle with Steve's guards, doing his best to break through to their Lord. He'd downed two of them but the others were standing firm. He was cut in many places, knife and spear wounds, but none fatal. Looking around, I saw Gannen Harst push Steve away from the threat. Steve was arguing with him – he wanted to take Vancha on.

Behind Steve and Gannen Harst, R.V. had let go of Debbie's rope and was backing away from her, shaking his head, hooks crossed behind his back, wanting no part of this. Debbie was tugging at her bonds, trying to wriggle free.

The two vampaneze holding me down saw Harkat and the others racing towards them. Cursing, they abandoned me and lashed out at their attackers. They were too swift for the ordinary circus folk – three died quickly – but Truska was part of the group, and she wasn't so easily despatched. She'd let her beard grow while she'd been waiting to fight – the unnatural blonde hair now trailed down past her feet. Standing back, she made the beard rise – she could control the hairs as though they were snakes – then directed the twisting strands towards one of the vampaneze. The beard parted into two prongs, then curled around the startled vampaneze's throat and tightened. He sliced at the hair and at Truska, but she had him too firmly in her grip. He fell to his knees, purple features darkening even further as he choked.

Harkat took on the other vampaneze, chopping at him with his axe. The Little Person lacked the speed of a vampaneze, but he was very powerful and his round green eyes were alert to his opponent's swift moves. He could fight as an equal, as he had many times in the past.

I circled around the vampaneze struggling with Vancha. I meant to go after Steve, but he and Gannen had linked up with three of the vampaneze who'd been roaming the grounds of the stadium. I didn't fancy the five-to-one odds, so I went to cut Debbie free instead.

"They surrounded the stadium shortly after Harkat and I arrived," she cried as I sliced through the ropes binding her arms. "I tried phoning, but it wouldn't work. It was Mr Tiny. He blocked my signal. I saw his watch glowing, and he was laughing."

"It's OK," I said. "We'd have come anyway. We had to."

"Is that Alice outside?" Debbie asked – the gunfire was deafening now.

"Yes," I said. "The vampirites seem to be enjoying their first taste of action."

Vancha lurched over to us, streaming blood. The vampaneze had given up on him and retreated, teaming up with the vampets and picking fights with the circus folk. "Where's Leonard?" Vancha bellowed.

I peered around the stadium but it was almost impossible to pick out any individuals in the press of bodies. "I had him in my sights a minute ago," I said. "He must be here somewhere."

"Not if Gannen flitted with him!" Vancha roared. He wiped blood clear of his eyes and looked for Steve and Gannen again.

"Are you badly wounded?" Debbie asked him.

"Scratches!" Vancha grunted. Then he shouted, "There.' Behind the fat man!"

He rushed forward, bellowing madly. Squinting, I caught a glimpse of Steve. He was close to the enormous Rhamus Twobellies, warily backing away from him. Rhamus was literally falling on his opponents, squashing them lifeless.

Debbie darted away from me, picked the bodies of the dead vampaneze clean of their weapons, and returned with an array of knives and two swords. She gave one of the swords to me and hefted the other herself. It was too large for her, but she held it steady, face set. "You go get Steve," she said. "I'll help the others."

"Be-" I began, but she'd already raced out of earshot, "-careful," I finished softly. I shook my head, smiled briefly, then set off after Steve.

Around me the battle was raging. The circus folk were locked in bloody combat with the vampets and vampaneze, fighting clumsily but effectively, blind fury compensating for lack of military training. The gifted freaks were a huge help. Truska was causing havoc with her beard. Rhamus was an immovable foe. Gertha Teeth was biting off fingers, noses, sword tips. Hans Hands had tucked his legs behind his neck and was dodging between the enemy forces on his hands, too low for them to easily strike, tripping them up and dividing them.

Vancha had come to a halt, held up by the fighting. He started firing shurikens at those enemies ahead of him, to clear a path. Jekkus Flang stepped up beside him and added his throwing knives to Vancha's stars. A deadly, efficient combination. I couldn't help thinking what a great show they could have put on if we'd been playing to an audience tonight instead of fighting for our lives.

Mr Tiny was picking his way through the mass of warring bodies, beaming merrily, admiring the corpses of the dead, studying the dying with polite interest, applauding those locked in especially vicious duels. Evanna was edging towards her father, disinterested in the carnage, bare feet and lower ropes stained with blood.

Gannen and Steve were still backing away from the massive Rhamus Twobellies, using him as a shield – it was hard for anybody else to get at them with Rhamus in the way. I tracked them like a hound, closing in. I was almost at the mouth of the tunnel through which we'd entered the stadium when fresh bodies burst through it. My insides tightened – I thought the police had come to the aid of their companions, meaning almost certain defeat for us. But then, to my astonished delight, I realized it was Alice Burgess and a dozen or so vampirites. Declan and Little Kenny – the pair who'd rescued me from the street when Darius shot me – were among them.
