Andrew only pops his head in once to ask if we need wine, to which Pippa responds, ‘I trained you so well,’ before she calls after him ‘and yes please! See if they have rosé!’

My sister finding out she had the BRCA gene? Pippa gasped with such a deep breath she practically choked.

Revealing that Millie asked me to go on her behalf and that I wasn’t really Millie, I was Andi, her non-marine-biologist younger sister? Pippa launched herself off the bed in disbelief.

Once wine was in hand, our conversation took a detour when I tried to explain to Pippa who Millie really was. When I told her about the time Millie tried to prank our mother by updating her phone to autocorrect all her texts to my dad with salacious phrases, Pippa giggled so hard she got hiccups.

The mixture of her laughter and the wine lifted my spirits, and I got off the bed to recreate Natalie’s interaction with me at the airport, which I completed by using one of Pippa’s bikini tops as a stand-in for Natalie’s glamorous scarf.

‘She’s like a movie star,’ Pippa sighed, ‘you’d actually quite like her.’

‘She’s going to out me!’

Pippa gripped her rosé tightly. ‘She wouldn’t dare.’

Hugh having a promotion riding on me not finding the fish I am looking for? Pippa sat back and furrowed her brow in anger.

‘But there’s one more thing,’ I said. ‘We kind of like . . .’ I trailed off, but Pippa looked at me knowingly.

‘You got some,’ she gasped. ‘In these tiny rooms?’

‘Well, technically we didn’t, but I did.’ I squealed, downing another gulp of my wine.

‘Tell me everything,’ she demanded.

I didn’t give her all the details, but I gave enough for her jaw to drop open, especially when I described the toe-curling bits. ‘Pippa, he was amazing.’

‘God bless whoever taught him how to do that,’ she said, lifting her hands in a prayer gesture towards the ceiling.

I didn’t need to explain how much I’ve fallen for Hugh – Pippa knows. But I did explain why I couldn’t bring myself to be honest with him – his past, and our argument, how much it killed me to have to tell him I didn’t feel the same way. That I couldn’t bear to betray Millie.

When I said, ‘I know it’s crazy to feel like this about someone after three days,’ Pippa fell straight back onto her pillows and said, ‘This is like something in a film,’ in such a heartfelt voice I thought she was going to start crying.

And then she sat straight up and said, ‘Well, we’d just better figure out a way to get you two to the last act.’ She downs the last sip of her wine before she continues.
