Claire climbed out, and was immediately grabbed by the man who’d been sitting beside her. ‘Hey!’ she protested, but that got her nowhere. So she looked around instead as he pulled her onward.

Farm hadn’t been code. It was an actual farm, and there was an actual barn and a square two-storey farmhouse with a porch. She hoped for the farmhouse, but instead they headed her off to the big, dark-red barn.

She expected hay and horse stalls, but inside, the structure had been turned into a lab, a nice one that had a thick concrete floor, clean-room walls, steel tables and cabinets and bright overhead lighting. It was full of equipment, too. Some of it Claire recognised, but a lot was new to her. Dr Davis took charge of the three vampires and had them led over to the right side of the large open space, where he had them manacled to large steel staples in the floor. All three promptly collapsed into protective crouches.

‘This way,’ her guard said, and dragged her left, after Irene Anderson.

That part of the lab was a replica of what Dr Anderson had at MIT, with a few changes; one of the most vivid being that two tables were neatly laid out with parts and schematics. Claire recognised one of them as being the constituent parts of VLAD; the second table, though, was different.

That was the pieces of the mod, Claire realised. This would tell her exactly what Dr Anderson had done to make her device into an offensive weapon. Claire picked up the plans and studied them, took each part and looked it over. She was still examining things when Dr Anderson thumped down the heavy weight of VLAD on the table … not the working one, she realised. That was still slung across Anderson’s chest.

This was the prototype model that hadn’t yet been upgraded.

‘I’m pretty sure you can figure this out,’ Anderson said. ‘The plans are right there. You wanted to be my lab assistant. Do your job. Any funny business, and I promise you, your boyfriend will suffer for it. Got it?’
