‘No, but we’re working on a few new leads. I’m afraid I need to ask a rather personal question but it could be directly related to Hayley’s kidnap.’ Dave noted the bewilderment on the doctor’s face, but as there was no polite way to introduce the subject, he continued, ‘I believe that you were having an affair before the kidnapping? Angela told me you’re estranged now because of another woman.’

Parks scowled, his thick eyebrows almost meeting in the middle. ‘Whatever has this got to do with Hayley?’

‘I need to know about the woman you were seeing – it’s just possible she may have been involved in some way with the kidnappers.’

‘How ridiculous. Has Angela put you up to this to get back at me?’ Parks appeared both embarrassed and angry.

‘No, she told me the affair was the reason you parted. I’m not asking out of curiosity, or to embarrass you, but because there’s a strong possibility this woman could be connected to the kidnappers.’

The doctor’s face paled. ‘No, I don’t believe it.’

‘Are you still seeing her?’

‘Not anymore, no. I’m honestly ashamed of what I did, especially when our family was going through so much. I told her we should stop seeing each other for a while and she agreed. I haven’t heard from her since.’

‘Can you give me her name and an address if you have one?’

‘Well yes, but I don’t know if she’ll still be there.’ Stuart Parks tore a sheet of paper off a pad on his desk, wrote the name and address down, and then passed it to Dave.

Chrissy Johnson, Apartment 2, Dene Court, Leeds. The name wasn’t the one Alex Radford had given Dave for the woman Stone was seeing, but then he wouldn’t expect her to use her real name.

‘Can you tell me when you last had any contact with her?’ Bennet asked.

‘It was while... Hayley was still missing, the second day I think. I rang Chrissy to tell her I couldn’t see her for a while. By then I knew it was a mistake – she was more concerned as to whether I’d continue paying the rent on her flat than what had happened to Hayley.’

‘You were paying for a flat?’

‘Yes, but not anymore, which is why I’m not sure if she still lives there.’

Dave was pretty sure she wouldn’t be there either. ‘And can you describe Chrissy to me?’

Stuart Parks sighed. ‘She’s about five foot five with long blonde hair and blue eyes. Quite striking really, with a good figure and always turned out well, which was regrettably at my expense.’ Parks was clearly suffering misgivings about the affair, but Dave knew he would feel so much worse if it turned out that this woman was connected to the kidnapping of his daughter.
