I knew it was going to be trickier to break into the school this time. They’d have beefed up the security in response to what had happened the night before. Beefed up the security? All they had to do was actually get some.

And they had. A police cruiser sat in the parking lot, its lights off. Just sitting there, the moonlight reflecting off the closed windows. The driver – doubtlessly some luckless rookie to have pulled so boring an assignment – was probably listening to music, though I couldn’t hear any from where I stood just outside the gate to the parking lot.

So I was going to have to find another way to get in. No biggie. I stashed the bike in some bushes, then took a leisurely stroll round the perimeter of the school.

There aren’t many buildings you can keep a fairly slender sixteen-year-old girl out of. I mean, we’re pretty flexible. I happen to be double-jointed in a lot of places, too. I won’t tell you how I managed to break in, since I don’t want the school authorities figuring it out – you never know, I might have to do it again someday – but let’s just say if you’re going to make a gate, make sure it reaches all the way to the ground. That gap between the cement and where the gate starts is exactly all the room a girl like me needs to wriggle through.

Inside the courtyard, things looked a lot different from the night before – and a whole lot creepier. All the floodlights were turned off – this didn’t seem like a very good safety precaution to me, but it was possible, of course, that Heather had blown all the bulbs – so the courtyard was dark and eerily shadowed. The fountain was turned off. I couldn’t hear anything this time except for crickets. Just crickets chirping in the hibiscus. Nothing wrong with crickets. Crickets are our friends.

There was no sign of Heather. There was no sign of anybody. This was good.

I crept, as quietly as I could – which was pretty quietly in my sneakers – to the locker Heather and I shared. Then I knelt down on the cold flagstones, and opened my backpack.

I lit the candles first. I needed their light to see by. Holding my lighter – OK, it wasn’t really my lighter, it was the long-handled lighter from the barbecue – to the candle’s bottom, I dripped some wax on to the ground, then shoved the candle’s base into the gooey dripping to keep it in place. I did this to each candle until I’d formed a ring of them in front of me. Then I peeled back the lid of the container holding the chicken blood.

I’m not going to write down the shape that I was required to paint in the centre of the ring of candles in order for the exorcism to work. Exorcisms aren’t things people should try at home, I don’t care how badly you might be haunted. And they should only be performed by a professional like myself. You wouldn’t, after all, want to hurt any innocent ghosts who happen to be hanging around. I mean, exorcizing Grandma – that won’t make you too unpopular, or anything.
