Carol frowned as she flicked back through her memories of criminals she’d gone head to head with over the years. She’d never worked with the Drugs Squad, but she’d encountered both dealers and mules more often than she could count when she’d been running the CID in the North Sea port of Seaford. None of them seemed to fit. The dealers were too cocky or too fucked up by their own product, the mules too lacking in initiative. Then she remembered Janine. ‘I think I’ve got someone,’ she said. ‘Janine Jerrold.’

‘Tell me about her.’

‘She started out as one of the hookers down at the docks. She was unusual, because she never had a pimp. She worked for herself, out of an upstairs room in a pub run by her aunt. By the time I came across her, she’d moved on to something a bit more lucrative and less physically dangerous. She ran a team of organized shoplifters. Occasionally, we’d lift one of the girls, but we never got our hands on Janine. Everybody knew she was behind it. But none of her girls would grass her up, because she always looked after them. She’d turn up to court to pay their fines, cash on the nail. And if they got sent down, she made sure their kids were looked after. She was smart, and she had so much bottle.’

Tony smiled. ‘OK, now we’ve got Janine in our sights. That’s the easy bit. What you have to do now is construct Janine for yourself. You need to mull over everything you’ve seen her do and say, and work out what ingredients went into the mix to make her the woman she is now.’

‘In four days?’

‘Obviously, it’s going to be a rough draft, but you can work something up in that time. Then comes the really hard bit. You’ve got to shed Carol Jordan and assume Janine Jerrold.’

Carol looked worried. ‘You think I’m up to it?’

He cocked his head on one side, considering. ‘Oh, I think so, Carol. I think you’re up to just about anything you set your mind to.’

There was a moment of silence, electric and pregnant. Then Tony jumped to his feet and said, ‘More coffee. I need more coffee. And then we need to plan what we’re going to do next.’

‘Next?’ Carol said, following him into the hall.

‘Yes. We haven’t got much time. We need to start role-playing right away.’
