‘That’s what I thought to begin with, but I’ve been thinking about it and there’s no indication he has another computer. Nothing copied or erased. And why would he store those details separately unless he had something to hide? It was his work computer, his only computer as far as I could see. You’d expect it to contain all his work files.’

‘There’s the one for my parents,’ Emma said, pointing. ‘Can I have a look?’

‘If you want.’ Ian opened the folder and waited as Emma read the information.

‘There’s a lot of medical jargon, but it’s more or less what Mum told me,’ Emma said at length.

Ian waited until she’d finished and then closed the file. He moved the cursor down to the last folder. ‘And this one is odd,’ he said, opening the folder titled Second Generation. ‘It’s a spreadsheet of couples, but we’re on it. There are our names and contact details.’

‘But why?’ Emma asked, staring at the spreadsheet. ‘My God! There are the dates our babies were born. Why would Moller have recorded those? How would he know? We’ve never been to his clinic.’

‘Exactly,’ Ian said. ‘I’ve been thinking about this all afternoon and the only conclusion I can come to is that this is a record of the grandchildren of those he’d treated. That’s why it’s called “Second Generation”. Their parents were the first generation. But why he should be collecting that type of data I’ve no idea, especially as we haven’t used the clinic. I don’t know if any of the others listed here did. And why did so many babies die?’

‘Can we report him?’ Emma asked with a shiver.

‘It would be difficult,’ Ian said. ‘We can’t disclose how I came by this information.’

‘What about reporting him anonymously to the police? You can do it online now.’

‘We’d need to show that a crime has been committed, and we can’t at present. There’s no evidence, but look at this last entry,’ Ian said, moving the cursor to the line containing the details of Grant and Chelsea Ryan. ‘They’re local and had a baby recently. I was thinking of phoning them to find out what their experience was of using the clinic. I’d have to think of a reason for having their details.’

‘Perhaps you could pretend you’re from the hospital healthcare team?’ Emma suggested. ‘I had someone call me after the miscarriages and offer counselling.’

Ian hesitated. ‘I don’t know. What would I say? I’m better with computers than people.’

‘I know.’ Emma managed a small, sad smile. ‘Shall I phone them?’

‘Do you think you could without giving us away?’

‘Yes, I think so. I know the sort of thing they say when they phone.’

‘Wouldn’t talking about our babies upset you?’ Ian asked, concerned.
