Dad and the children are watching a DVD, although he’s fallen asleep, in spite of the dragons and the explosions. Chloe is curled up on the sofa next to them, her arm round Lotte, looking like a child again. I notice a book, the pages curled back, sticking out from under the chess set. I slide it out. It’s Dante’s Divine Comedy. Luca must have left it behind. I’ve just started flicking through it when I hear the crunch of tyres.

It’s a Lamborghini. I let the two officers in, and introduce the Maggiore and the Capitano.

‘This is Matt Jenkins, Amy’s husband and my brother-in-law. My dad, David Flowers; Chloe Jenkins-Yu, Matt’s daughter; the kids are his and Amy’s: Theo and Lotte.’

‘No one else is here?’ asks Ruggieri.

He’s softly spoken and it’s a polite enquiry, but there’s something about him – his height, his military bearing, maybe the weapon he’s carrying – that makes it seem like a threat. I shake my head, but I add that we also had Luca and Joe staying with us, and why they’d left the island. He nods impatiently – Amy must have told him this already.

‘My wife is upstairs,’ Matt says.

‘Is that a real gun?’ asks Theo.

‘The pistola. We have the Beretta AR70 in the car,’ Ruggieri says.

‘Cool!’

‘Coffee?’

‘Si. Grazie.’

Amy comes downstairs, her face pinched with worry.

‘Do you have any idea who could have done this to my sister?’

‘We investigate.’

I put the kettle on and set out the cafetière. ‘The photos!’ I say. I’d completely forgotten.

‘What photos?’ Amy asks.

‘I saw some creepy pictures of Chloe, when I found her iPad after it had gone missing. I meant to say, but… well, there was the anniversary, and then Bethany disappeared. They looked as if Chloe didn’t know she was being photographed, but I wasn’t sure. Sorry, I’m an idiot. I should have told you earlier.’

‘What were you doing looking at my iPad?’ Chloe asks, sitting up and pushing Lotte off her.

‘Sorry, Chlo. I saw them accidentally when I found your iPad and I opened it to check it was okay. I was going to ask you.’

‘And this is relevant?’ asks Ruggieri.

I shrug. ‘It’s suspicious. Maybe whoever took them might have been responsible for attacking Bethany.’

‘Show me.’

Chloe sullenly opens Photos on her iPad and passes it over to the Maggiore.

‘Who is this?’ Ruggieri asks, pausing over the one of Chloe and Carlo goofing around at his farm.

‘Carlo Donati,’ Chloe says.

‘His family rented the holiday house to us,’ Matt explains. ‘All our dealings with the Donatis have been through Carlo.’

‘Did you see him on the day that Betany goes missing?’

Amy starts to speak. ‘In the evening, at the terrace bar in the vineyard—’ when Chloe cuts across her.

‘Yes.’
