I went back upstairs and cleared the mess up as best I could, then went back to my own room. I sat on the bed and stared through the window, feeling terrified and alone. Was Alice already possessed? After all, it had been Mother Malkin’s face staring back out of the mirror. If she was, then the baby and everyone else was in real danger.

She hadn’t tried to do anything then, but Alice was relatively small compared with Jack, so Mother Malkin would have to be sly. She’d wait for everyone to go to sleep. I’d be the main target. Or maybe the baby. A child’s blood would increase her strength.

Or had I broken the mirror just in time? Had I broken the spell at the very moment when Mother Malkin was about to possess Alice? Another possibility was that Alice had just been talking to the witch, using the mirror. Even so, that was bad enough. It meant I had two enemies to worry about.

I needed to do something. But what? While I sat there, my head whirling, trying to think things through, there was a tap on my bedroom door. I thought it was Alice so I didn’t go. Then a voice called my name softly. It was Ellie, so I opened the door.

‘Can we talk inside?’ she asked. ‘I don’t want to risk waking the baby. I’ve only just got her off to sleep again.’

I nodded, so Ellie came in and carefully closed the door behind her.

‘You all right?’ she asked, looking concerned.

I nodded miserably but couldn’t meet her eyes.

‘Would you like to tell me about it?’ she asked. ‘You’re a sensible lad, Tom, and you must have had a very good reason for what you did. Talking it through might make you feel better.’

How could I tell her the truth? I mean, Ellie had a baby to care for, so how could I tell her that there was a witch somewhere loose in the house with a taste for children’s blood? Then I realized that, for the sake of the baby, I would have to tell her something. She had to know just how bad things were. She had to get away.

‘There is something, Ellie. But I don’t know how to tell you.’

Ellie smiled. ‘The beginning would be as a good a place as any…’

‘Something’s followed me back here,’ I said, looking Ellie straight in the eyes. ‘Something evil that wants to hurt me. That’s why I broke the mirror. Alice was talking to it and-’

Ellie’s eyes suddenly flashed with anger. ‘Tell Jack that, and you certainly would feel his fist! You mean you’ve brought something back here, when I’ve got a new baby to care for? How could you? How could you do that?’

‘I didn’t know it was going to happen,’ I protested. ‘I only found out tonight. That’s why I’m telling you now. You need to leave the house and take the baby to safety. Go now, before it’s too late.’

‘What? Right now? In the middle of the night?’

I nodded.

Ellie shook her head firmly. ‘Jack wouldn’t go. He wouldn’t be driven out of his own house in the middle of the night. Not by anything. No, I’ll wait. I’m going to stay here and I’m going to say my prayers. My mother taught me that. She said that if you pray really hard, nothing from the dark can ever harm you. And I really do believe that. Anyway, you could be wrong, Tom,’ she added. ‘You’re young and only just beginning to learn the job, so it may not be quite as bad as you think. And your mam should be back at any time. If not tonight, then certainly tomorrow night. She’ll know what to do. In the meantime, just keep out of that girl’s room. There’s something not right about her.’

As I opened my mouth to speak, intending to have one more go at persuading her to leave, an expression of alarm suddenly came over Ellie’s face and she stumbled and put her hand against the wall to save herself from falling.

‘Look what you’ve done now. I feel faint just thinking about what’s going on here.’

She sat down on my bed and put her head in her hands for a few moments, while I just stared down at her miserably, not knowing what to do or say.

After a few moments she climbed back to her feet again. ‘We need to talk to your mam as soon as she gets back, but don’t forget, stay away from Alice until then. Do you promise?’

I promised, and with a sad smile Ellie went back to her own room.

It was only when she’d gone that it struck me…

Ellie had stumbled for a second time and said she’d felt light-headed. One stumble could be just chance. Just tiredness. But twice! She was dizzy. Ellie was dizzy and that was the first sign of possession!

I began to pace up and down. Surely I was wrong. Not Ellie! It couldn’t be Ellie. Maybe Ellie was just tired. After all, the baby did keep her awake a lot. But Ellie was strong and healthy. She’d been brought up on a farm herself and wasn’t one to let things drag her down. And all that talk about saying prayers. She could have said that so that I wouldn’t suspect her.

But hadn’t Alice told me that Ellie would be difficult to possess? She’d also said that it would probably be Jack, but he hadn’t shown any sign of dizziness. Still, there was no denying that he had become more and more bad tempered and aggressive too! If Ellie hadn’t held him back he’d have thumped my head off my shoulders.

But of course, if Alice were in league with Mother Malkin, everything she said would be intended to put me off the scent. I couldn’t even trust her account of the Spook’s book! She could have told me lies all along! I couldn’t read Latin so there was no way to check what she’d said.

I realized that it could be any one of them. An attack could occur at any moment and I hadn’t any way of knowing who it would come from!

With luck, Mam would be back before dawn. She’d know what to do. But dawn was a long time off so I couldn’t afford to sleep. I’d have to keep watch all night long. If Jack or Ellie were possessed, there was nothing I could do about it. I couldn’t go into their room, so all I could do was keep an eye on Alice.

I went outside and sat on the stairs between the door to Ellie and Jack’s room and my own. From there I could see Alice’s door below. If she left her room, at least I’d be able to give a warning.

I decided that if Mam wasn’t back, I’d leave at dawn; apart from her, there was just one more chance of help…

It was a long night, and at first I jumped at the slightest sound – a creak of the stairs or a faint movement of the floorboards in one of the rooms. But gradually I calmed down. It was an old house and these were the noises I was used to – the noises you expected as it slowly settled and cooled down during the night. However, as dawn approached, I started to feel uneasy again.

I began to hear faint scratching noises from inside the walls. It sounded like fingernails clawing at stone and it wasn’t always in the same place. Sometimes it was further up the stairs on the left; sometimes below, close to Alice’s room. It was so faint that it was hard to tell whether I was imagining it or not. But I began to feel cold, really cold, and that told me that danger was near.

Next the dogs began to bark, and within a few minutes the other animals were going crazy too, the hairy pigs squealing so loud you’d have thought the pig butcher had already arrived. If that wasn’t enough, the row started the baby crying again.

I was so cold now that my whole body was shaking and trembling. I just had to do something.

On the riverbank, facing the witch, my hands had known what to do. This time it was my legs that acted faster than I could think. I stood up and ran. Terrified, my heart hammering, I bounded down the stairs, adding to the noise. I just had to get outside and away from the witch. Nothing else mattered. All my courage had gone.
