‘Not at all,’ Anderson said. ‘This thing, if it works, is far too dangerous to be in Morganville, or anywhere that Amelie can get to it. In fact, there’s a strong possibility that—’ She paused, because a soft musical tone sounded in the lab, and she swivelled to face a computer monitor set in the wall behind them, concealed from easy view by a half wall. On the monitor, striding down the hallway, was a tight knot of four people, all dressed identically – no, not really, but all in dark suits that seemed identical at first glance. Three men and a woman. Her suit had a skirt, and midheel shoes, and she lacked a tie, but that was really the only way the four of them differed.

‘Claire, take VLAD,’ Anderson said. She kept watching the monitor for a few more seconds, then nodded as if she’d confirmed her suspicions. ‘Come on.’

Claire scooped up the heavy weight and hustled after Dr Anderson as she moved around lab tables to a blank white wall … and then pressed her hand to an almost invisible panel that was set in it, white on white. It lit up with a shimmering silver glow, and a panel slid open.

There were shelves behind it. Most were crowded with labelled boxes and bottles, but there was a large empty shelf in the bottom, and Claire quickly knelt and slid VLAD into the space. As she pulled back, Anderson pressed her hand on the locking mechanism again, and the door slid shut with barely a whisper.

‘Say nothing,’ Anderson said. ‘If they ask you a direct question, just tell them you don’t know anything about the research, you just arrived. It’s true. Whatever you do, don’t lie to them, but tell them as little as you can possibly get away with.’

‘But – who are they?’

‘Let’s hope you never need to know. I sincerely don’t want to involve you in things above your pay grade.’

That was all there was time for, because the outer door slid open, and the first of the four stepped through. They obviously knew the protocol, too. The tallest man came through first, and nodded to Anderson as he stepped aside. He had cool, assessing brown eyes that flicked over Claire briefly before focusing back on the professor.

The other three came in quick succession, each nodding and politely waiting until the last had joined them. The last was a midsize man in a pale blue shirt and bright blue tie – just a shade more unconventional than the others in the group. He walked forward, extending his hand to Dr Anderson.

‘Irene,’ he said, and smiled. ‘Good to see you again.’

‘You too, Charles. To what do I owe this visit?’

‘Just a spot check, the usual stuff.’ He shrugged. ‘You understand how it goes. Protocol.’
