‘It’s soooo obvious you guys like each other.’

‘Yeah, but . . . that’s the thing. I, like, can’t like him. I mean I shouldn’t . . . I mean . . .’ I can’t fall for someone who thinks I’m my sister. How would I ever explain to Millie that I destroyed her professional reputation for a fling?

Pippa’s eyes widen. ‘Why shouldn’t you? Are you . . .’ Now it’s her turn to trail off. I can practically see the wheels in her brain turning. ‘You’re not already bloody with someone?’

‘That would be less complicated than my current situation . . . And no, actually. I broke up with my boyfriend a couple of months ago.’ My shoulders slump, it might have been a few months but it feels like a lifetime. It’s also incredibly confusing to blur my own life with Millie’s, I’m starting to feel like Andi doesn’t even exist.

‘And you don’t want to rush into things,’ Pippa supplies.

It’s easier for me to let her believe that’s the reason, even though not even the half of it. ‘Exactly,’ I agree with Pippa.

‘That’s understandable,’ she says warmly, not catching on that I’m not telling the full story. ‘But it would be a shame to miss the perfect rebound opportunity.’

‘Right,’ I say half-heartedly.

I excuse myself to rinse off. On the way, I almost thwack my head into the door frame because I’m so distracted by my conversation with Pippa. I duck around the dining table on autopilot, steadying my hand on the vinyl bench as the boat rocks with the waves. Would it be crazy to tell Pippa about the whole pretending to be Millie thing? I’m thinking, as I ease into our tiny cabin.

I notice that, for once, Hugh’s stuff is spilling out of his duffel, and I’m relieved he isn’t as neat as I thought he was. My belongings have been dumped entirely across the twin mattress.

I shimmy out of my bikini and grab for my towel, mentally preparing to have to crouch under lukewarm water and not feel like I’ve washed all the conditioner out of my hair. I’m moving slowly, still running a pros and cons list for whether or not I should tell Pippa. Pros: I won’t be in this alone and she gives good advice. Cons: I don’t actually know if I can trust her, and if I blow this, Millie will kill me.

Lost in thought, I’m still wrapping my towel around my body when I open the door to head to the shower.

The boat lurches just as I step out of my room and I fall directly on top of Hugh, somehow managing to dislodge my half-wrapped towel in the process.
