That lunchtime the teenagers gathered around the computer in Isabelle’s study, trying to get all the gossip they could, trying to piece together what had happened from Facebook and Twitter. There wasn’t much news – the police hadn’t made any public statements since the one they’d issued this morning, confirming she was missing. It seemed Lorne had last been seen by her mother yesterday afternoon when she’d headed into town, on foot, for a shopping expedition. Her Facebook page hadn’t been updated in that time and no calls had been made on her mobile: apparently, when her parents had rung, the phone was switched off.

‘It could just be a tiff,’ Isabelle said, when the kids had gone back outside. ‘Fed up with her parents, run off with a boyfriend. I did it when I was that age – teach your parents a lesson, that sort of thing.’

‘Probably,’ agreed Sally. ‘Maybe.’

It was nearly one thirty. Time to get going. She began to pack up her things, thinking about Lorne. She’d met her only a handful of times, but she recalled her as a determined girl, with a slightly sad air. She remembered sitting in the garden with her one day, when she and Millie were still living with Julian in Sion Road, and Lorne saying, quite out of the blue, ‘Millie’s so lucky. You know – for it to be just her.’

‘Just her?’

‘No brothers or sisters.’

That had come as a surprise to Sally. ‘I thought you got on with your brother.’

‘Not really.’

‘Isn’t he kind to you?’

‘Oh, yes, he’s very kind. He’s kind. And he’s nice. And he’s clever.’ She pushed her hair away from her pretty face. ‘He’s perfect. Does everything Mum and Dad want. That’s what I mean. Millie’s lucky.’
