Annie sank back into her chair, unable to respond.

"It was Steve," Darius said. "Steve who got me into trouble, who killed the snake-boy, who made Darren come back to see you. Darren didn't want to – he knew he'd hurt you – but Steve left him with no choice. It's true, Mum, everything he said. You've got to believe us, because it was Steve, and I think he might come back – come after you – and if we aren't ready… if you don't believe…"

He ground to a halt, running out of words. But he'd said enough. When Annie looked at me again, there was fear and doubt in her eyes, but no scorn. "Steve?" she moaned. I nodded unhappily and her face hardened. "What did I tell you about him?" she screamed at Darius, grabbing the boy and shaking him angrily. "I told you never to go near him! That if you ever saw him, you had to run and tell me! I said he was dangerous!"

"I didn't believe you!" Darius cried. "I thought you hated him just because he ran away, that you were lying! He was my dad!" He tore himself away from her and collapsed on the floor, weeping. "He was my dad," he sobbed again. "I loved him."

Annie stared at Darius crying. Then she stared at me. And then she also started to cry, and her sobs were even deeper and more painful than her son's.

I didn't cry. I was saving my tears. I knew the worst was yet to come.

Later. After the tears. Sitting around the living room. Annie had recovered from the worst of the shock. All three of us were drinking hot chocolate. I hadn't called the others in yet – I wanted some personal time with Annie before I dumped the full fallout from the War of the Scars upon her.

Annie made me tell her more about my life. She wanted to hear about the countries I'd visited, the people I'd met, the adventures I'd had. I told her some of the highlights, leaving out the darker aspects. She listened, dazed, touching me every few minutes to make sure I was real. When she heard I was a Prince, she laughed with delight. "Does that make me a princess?" she smiled.

"Afraid not," I chuckled.

In return, Annie told me what her life had been like. The hard months after I'd 'died'. Slowly returning to normal. She was young, so she recovered, but Mum and Dad never really got over it. She raised the question of whether or not they should be told I was alive. Then, before I could speak, she said, "No. They're happy now. It's too late to change the past. Best not to drag it up again."

I paid close attention when she spoke about Steve. "I was a teenager," she said angrily, "mixed-up and unsure of myself. I had some friends but not many. And no serious boyfriend. Then Steve came back. He was only a few years older than me, but he looked and acted grown-up. And he was interested in me. He wanted to talk to me. He treated me like an equal."

They spent a lot of time together. Steve put on a good act – kind, generous, loving. Annie thought he cared for her, that they had a future together. She fell in love with him, and gave her love to him. Then she found out she was expecting a baby.

"His face lit up when he heard," she said, shivering from the memory. Darius was by her side, solemn, silent, listening intently. "He made me believe he was delighted, that we'd get married and have lots of children together. He told me not to tell anyone – he wanted to keep it secret until we were husband and wife. He went away again. He said it was to earn money, to pay for our wedding and the baby's upkeep. He stayed away a long time. He returned late one night, while I was sleeping. Woke me up. Before I could say anything, he clamped a hand over my mouth and laughed. 'Too late to stop it now!' he mocked me. He said other things, horrible things. Then he left. I haven't heard from him since."

She had to tell Mum and Dad about the baby then. They were furious – not with her, but with Steve. Dad would have killed Steve if he'd found him. But nobody knew where Steve was. He'd vanished.

"Raising Darius was hard," she smiled, ruffling his hair, "but I wouldn't give up a day of it. Steve was wicked, but he gave me the most marvellous gift anyone could have ever given me."

"Soppy old cow," Darius grunted, fighting hard not to smile.

I was quiet a long time after that. I wondered if Steve had meant to use Darius against me even then. This was back before he met the vampaneze and learnt of his abominable destiny. But I bet he was already planning my downfall, one way or the other. Did he deliberately get Annie pregnant, so he could use his nephew or niece to hurt me? Knowing Steve as I did, I guessed those were his exact intentions.

Annie started telling me about her life with Darius, from how Mum and Dad helped rear him until they moved away, how the pair were managing now on their own. She worried about him not having a father, but her experience with Steve had made her wary of men, and she found it hard to trust anyone. I could have listened to Annie talk all night, telling tales about Mum, Dad and Darius. I was catching up on all those missed years. I felt like part of the family again. I didn't want it to stop.

But we were in the middle of a crisis. I'd delayed the moment of truth, but now I had to tell her about it. The night was drawing on, and I was keen to conclude the business I'd come about. I let her finish the story she was telling – about Darius's first week in school – then asked if I could introduce her to some of my friends.

Annie wasn't sure what to make of Vancha, Alice and Evanna. Alice dressed normally, but Vancha in his animal hides, with his straps of throwing stars and green hair, and the hirsute, deliriously ugly Evanna draped in ropes… They would have stuck out like a couple of gargoyles anywhere!

But they were my friends (well, Vancha and Alice were, whatever about the witch), so Annie welcomed them – though I could tell she didn't entirely trust the trio. And I knew she sensed they weren't here just to make up the numbers. She guessed that something bad was coming.

We made small talk for a while. Alice told Annie about her years on the police force, Vancha described some of his Princely duties and Evanna gave her tips on how to breed frogs (not that Annie had any interest in that!). Then Darius yawned. Vancha looked at me meaningfully – it was time.

"Annie," I started hesitantly, "I told you Darius pledged himself to the vampaneze. But I didn't tell you what precisely that means."

"Go on," Annie said when I stalled.

"Steve blooded him," I said. "He transferred some of his vampaneze blood to Darius. The blood isn't very strong within him, but it will strengthen. The cells will multiply and take over."

"You're saying he'll become like you?" Annie's face was ashen. "He won't age normally? He'll need to drink blood to survive?"

"Yes." Her face crumpled – she thought that was the worst, the part I'd been holding back. I wished I could spare her the truth, but I couldn't. "There's more," I said, and she stiffened. "Vampires can control their feeding habits. It isn't easy – it requires training – but we can. Vampaneze can't. Their blood forces them to kill every time they feed."

"No!" Annie moaned. "Darius isn't a killer! He wouldn't!"

"He would," Vancha grunted. "He'd have no choice. Once a vampaneze gets the taste of blood, his urges consume him. He goes into a kind of trance and feeds until he's drained the source dry. He can't stop."

"But there must be some way to help him!" Annie insisted. "Doctors… surgery… medicine…"

"No," Vancha said. "This isn't a human disease. Your doctors could study him, and restrain him while he was feeding – but do you want your son to spend his life imprisoned?"
