Pete grabbed it off the table with a little too much force, and packing peanuts exploded into the air in a spontaneous snowfall. Jesse laughed and grabbed at them as they fell, and then they were all scooping up the feather-light foam chunks, chasing them around the floor since the slightest breath could move them, and generally laughing like fools as they did. It was weirdly relaxing, and by the time the mess was back in the box, and the box in Pete’s big hands, Claire felt breathless and more at ease than she’d been in days. Shared laughter did that, even when you didn’t really know the people you were sharing it with.

‘We should go,’ Pete finally said, and nodded to Dr Anderson. ‘Irene. See you at the bar sometime?’

‘Soon,’ Anderson agreed. She nodded back to Pete, then to Jesse. For Jesse, she added a wink. ‘Both of you, take care. I don’t know why, but my instincts tell me we’re going to be up against it pretty soon. And I always listen to my instincts.’

‘Hell yeah.’ Jesse winked at her, smiled at Claire, and strode out of the lab, all long legs and swinging long hair. Pete waited for the door to cycle and followed, and in the sudden silence, the place felt very empty, quiet and sterile.

Although a lone packing peanut had escaped to roll around on the floor, which made Claire feel a little bubbly giggle inside. She kept it down, though, because Dr Anderson’s smile had disappeared, and she was all business as she peered at Claire’s device.

‘What do you call this thing?’ Dr Anderson asked her, and gently touched some of the oddly angled gauges and gears.

‘The Vampire Levelling Adjustment Device,’ Claire said. ‘VLAD, for short. Well, that was what I was considering calling it, anyway.’

‘VLAD,’ Anderson repeated, and smiled. ‘Really.’

‘My boyfriend liked it.’

‘Your boyfriend has a questionable sense of humour.’

‘He’d be the first to agree with you about that,’ Claire said. She’d rolled her eyes when Shane had popped out with that name, off the cuff, but now she thought it was spectacularly appropriate. VLAD. She could totally see it.

So could Dr Anderson, it seemed, because she slowly raised an eyebrow and drew a manicured fingernail along the barrel. ‘VLAD,’ she said again. ‘Yes. I think it seems like the right thing, after all. So. Break it down for me, Claire. How exactly does this work?’
