‘How do you know that?’

‘Not magic, if that’s what you’re thinking,’ I said airily. ‘I know it because I’m a super-awesome sleuth with immense powers of deduction.’

Winter exhaled. ‘Ivy…’

‘The set is closed,’ I explained. ‘It’s pretty hard for someone to gain access to it. Not impossible, but difficult. I wouldn’t bother. But then, that’s me. However there are a few blind spots around the back of the trailers where it’s possible to clamber over the fence.’ I began to tick off on my fingers. ‘First of all, none of the crew members are missing so the blood doesn’t belong to anyone involved in Enchantment. Secondly, security was complaining earlier about a sheep trying to get inside. Thirdly,’ I finished with a flourish, ‘on top of the fence and almost directly behind Bellows’ trailer, there’s evidence that wool has snagged.’ I paused. ‘And we all know how much you love evidence.’

Winter stared at me. ‘So what you’re saying is that a sheep tried to get access and was foiled by security so climbed over the fence instead, which is … how high?’

I considered. ‘About two metres.’

‘So this sheep climbed over a two-metre high fence, walked through Bellows’ door—’

‘Went through the rear window, actually,’ I interrupted.

Winter gave me a long-suffering look. ‘Fine. Went through the window, hit a crew member over the head, slit its own throat, disposed of its own body and created enough havoc to stop Enchantment from filming.’

I smiled. I hadn’t told him about my pièce de resistance. ‘This sheep also drew a pentagram on the wall of Bellows’ trailer.’

His spine stiffened. ‘A pentagram?’

‘Yep.’ I reached over and grabbed his pint glass, taking a long swig and smacking my lips. I deserved it. ‘A crude one but definitely a pentagram. Obviously, someone bewitched the sheep to do all this.’

‘So, in your infinite wisdom, Ivy,’ he said, ‘what’s the motive for all this?’

I shrugged. ‘I don’t know. I figured I’d leave that part to you.’

Winter snatched his drink back from me. Boo. ‘Have you ever tried to bewitch a sheep?’

‘No. I don’t meet many sheep in Oxford. I tried it on Brutus once. I attempted to bewitch him so that he’d go and buy his own cat food.’

‘You attempted?’

‘Yeah. It didn’t work.’

Winter rolled his eyes. ‘You’re probably the most naturally talented witch I’ve ever met, Ivy, even if you do let those talents go to waste. If you can’t bewitch your own familiar, how would someone else manage to bewitch a sheep? Even if they could, how could they bewitch a sheep to scale two-metre high fences?’

I opened my mouth to speak but he held up a hand to forestall me. ‘If it really is sheep’s blood, then someone brought the sheep over and killed it in Bellows’ trailer.’ He rubbed his chin. ‘Although what they did with the body is anyone’s guess. Perhaps Bellows is the next target and this is a warning.’
