‘Hi, Claire. You don’t know me, but don’t hang up. Irene Anderson asked me to drop in and take you to her lab. My name is Jesse.’ She sounded calm and relaxed, and had a slightly exotic accent, something that vaguely reminded her of the Deep South, but it was well concealed. ‘My friend Pete and I will be there around six.’

‘That’s late,’ Claire said, surprised. ‘I thought she wanted me to get it to her as soon as possible.’

‘Day jobs, they do throw a crimp in your social life,’ Jesse said, and chuckled. It was a warm rumble of a sound, and despite her current on-alert-for-trouble attitude, she found herself liking the other girl for it. ‘Coming as fast as we can. Oh, and she said you might be a little trigger happy, so please, don’t shoot. We come in peace, and I’d rather not go in pieces.’

‘I promise to ask questions first,’ Claire said. Jesse laughed again, and hung up.

And she did ask questions. She called Dr Anderson, who confirmed straight away that Jesse and Pete were known to her. Claire hadn’t really doubted it, but she was still worried about Derrick; it seemed unlikely he knew about Dr Anderson and the escort she’d ordered up, but just now, paranoia was an advantage.

She spent the spare few hours studying, surfing the ’net, and wondering – worrying – about where Shane was, and what he was doing. She’d had an e-mail, she saw – not a video this time, just plain text, telling her that he had a new phone number, and giving it to her. She memorised it and put it into her phone and logged it in her computer in her private phone list – her usual triple backup plan – and was considering calling him (just to be sure the number was right, of course).

Just as she hovered her finger over his name in the address book, though, she heard a loud knock on the door. Her gaze jerked up. It was – surprisingly – six o’clock, and they were right on time.

She still checked the peephole before she began clicking back the locks. Not Derrick, for sure; a boy and girl, both a little older than she was. The girl was the one who drew the attention first, because she was tall, well built, and had fiery red hair that fell in shining waves almost to her waist. She was also – like Eve – Goth style, with lots of black eyeliner, pale make-up, and unnaturally coloured lips. Skulls and leather featured heavily in her outfit.

Claire eased the door open just a bit and said, ‘Jesse and Pete?’
