Lindsey held out her arms and he settled onto her knee.

‘He’s got a bug,’ she said. ‘That’s why he’s off school. I had to take a sick day.’

‘Where do you work?’ Dudek said.

‘I’m a nurse. His dad works away, so he can’t be here.’

‘Who are you?’ the boy said.

‘Wynne. My name is Jane Wynne.’

‘She’s a detective,’ Lindsey said. ‘This is the first detective you’ve met, Josh.’

‘You’re a detective?’ Josh said.

‘I am.’

‘Who are you detecting?’ he said.

‘That’s a long story. I’m sorry you don’t feel well. But if you’re hungry, that’s a good sign.’ Wynne smiled at Lindsey. ‘Why don’t you get him something to eat. We won’t be too long, I hope.’

While Lindsey was in the kitchen, Wynne took the opportunity to take a look around the room. There were a number of photos of Lindsey, a tall, wiry man with curly dark hair, and Josh. There was also one of her and the man on their wedding day.

It didn’t look like the home of someone bent on revenge for a decade-old slight, but then appearances, as Wynne had learned many times, meant nothing.

Lindsey came back and sat down.

‘He’s happy now,’ she said. ‘So how can I help?’

‘We’re trying to establish if anyone had a motive for hurting Annabelle Westbrook,’ Wynne said. ‘And we wanted to discuss your relationship with her.’

‘We don’t have a relationship,’ Lindsey said.

‘But you do know each other,’ Wynne said.

‘And you did attend the christening of her first son,’ Dudek added.

Lindsey rubbed her temples.

‘God, I can’t believe that’s coming back to haunt me,’ she said. ‘I was hoping it was in the past.’

‘Can you tell us what happened?’ Wynne said.

‘I don’t know what happened,’ she said. ‘It’s so embarrassing. I was in a rough patch and somehow I thought it was a good idea to go there.’

‘You thought it was a good idea to crash a party after the christening of your ex’s first son?’ Dudek said.

‘Would you believe me if I said that I was intending to wish them all the best? Even though I was having a really hard time back then, I still knew I owed Matt an apology. And I was thinking that I’d show up and apologize and say all the best and let’s let bygones be bygones. But that’s not what happened.’

‘What did happen?’ Wynne said.

‘I got there and saw them and realized that they didn’t want my apologies. I was nothing to them. They hadn’t given me a thought. And I just lost it. I’d been drinking, too, which didn’t help.’

‘Why were you having a hard time?’ Wynne said.
