I felt frozen, my hand clutching my passport like I was about to go somewhere else. I had to remind myself to breathe.

‘Well, we thought you might like a special dinner,’ Will’s father said. ‘There’s a jolly nice restaurant at the Intercontinental. Champagne on us. What do you think? Your mother and I thought it might be a nice treat.’

‘Sure,’ said Will. He was smiling at his mother and she was looking back at him as if she wanted to bottle it. How can you? I wanted to yell at him. How can you look at her like that when you already know what you are going to do to her?

‘Come on, then. I’ve got the car in disabled parking. It’s only a short ride from here. I was pretty sure you’d all be a bit jet-lagged. Nathan, do you want me to take any of those bags?’

My voice broke into the conversation. ‘Actually,’ I said – I was already pulling my luggage from the trolley – ‘I think I’m going to head off. Thank you, anyway.’

I was focused on my bag, deliberately not looking at them, but even above the hubbub of the airport I could detect the brief silence my words provoked.

Mr Traynor’s voice was the first to break it. ‘Come on, Louisa. Let’s have a little celebration. We want to hear all about your adventures. I want to know all about the island. And I promise you don’t have to tell us everything.’ He almost chuckled.

‘Yes.’ Mrs Traynor’s voice had a faint edge to it. ‘Do come, Louisa.’

‘No.’ I swallowed, tried to raise a bland smile. My sunglasses were a shield. ‘Thank you. I’d really rather get back.’

‘To where?’ said Will.

I realized what he was saying. I didn’t really have anywhere to go.

‘I’ll go to my parents’ house. It will be fine.’

‘Come with us,’ he said. His voice was gentle. ‘Don’t go, Clark. Please.’

I wanted to cry then. But I knew with utter certainty that I couldn’t be anywhere near him. ‘No. Thank you. I hope you have a lovely meal.’ I hoisted my bag over my shoulder and, before anyone could say anything else, I was walking away from them, swallowed up by the crowds in the terminal.

I was almost at the bus stop when I heard her. Camilla Traynor, her heels clipping on the pavement, half walked, half ran towards me.

‘Stop. Louisa. Please stop.’

I turned, and she was forcing her way through a coach party, casting the backpacking teenagers aside like Moses parting the waves. The airport lights were bright on her hair, turning it a kind of copper colour. She was wearing a fine grey pashmina, which draped artistically over one shoulder. I remember thinking absently how beautiful she must have been, only a few years earlier.

‘Please. Please stop.’

I stopped, glancing behind me at the road, wishing that the bus would appear now, that it would scoop me up and take me away. That anything would happen. A small earthquake, maybe.

‘Louisa?’

‘He had a good time.’ My voice sounded clipped. Oddly like her own, I found myself thinking.

‘He does look well. Very well.’ She stared at me, standing there on the pavement. She was suddenly acutely still, despite the sea of people moving around her.

We didn’t speak.

And then I said, ‘Mrs Traynor, I’d like to hand in my notice. I can’t … I can’t do these last few days. I’ll forfeit any money owed to me. In fact, I don’t want this month’s money. I don’t want anything. I just –’

She went pale then. I saw the colour drain from her face, the way she swayed a little in the morning sunshine. I saw Mr Traynor coming up behind her, his stride brisk, one hand holding his panama hat firmly on his head. He was muttering his apologies as he pushed through the crowds, his eyes fixed on me and his wife as we stood rigidly a few feet apart.

‘You … you said you thought he was happy. You said you thought this might change his mind.’ She sounded desperate, as if she were pleading with me to say something else, to give her some different result.
