‘You got my surprise then,’ he says to Evie. ‘You must be Magda,’ he adds, and in return Magda squeals again.

Evie and Magda sit in the corner Evie picked out earlier, two empty coffee cups apiece and neither of them showing any signs of easing up on the talking any time soon. Evie still cannot believe her best friend in the whole world is sat opposite, in the lobby of a Bavarian hotel with her, telling her Duke flew her out here.

‘I honestly thought it was a joke,’ Magda says. ‘He has one of those blue ticks on Instagram, so I’m like, okay, it’s not a fan account but maybe his real account got hacked? Or maybe I’m misunderstanding everything? But his assistant got him to record a video of him verbally telling me that he’d love to get me out here because he knows how much you want to share it with me.’

‘True,’ says Evie. ‘I did tell him that, yes.’

‘They sent a car, and I turned left on the plane, which is insane by the way. They have proper glasses in first class! I ate better on that KLM flight than I have done in most restaurants! And the whole time I’m telling myself this was paid for by Duke Carlisle. Like … seriously?’

‘I’m starting to see that he’s very kind like that,’ Evie says. ‘I’m sorry he couldn’t stay. He doesn’t get to decide his schedule, but we can all go for dinner tonight, maybe, if they’re done in time?’

Magda waves a hand. ‘If he was here, we wouldn’t be able to talk about him,’ she whispers conspiratorially. ‘And I am desperate to talk about him.’

‘Come on,’ Evie instructs. ‘Let’s put your stuff in my room and see the sights. Have you ever had Dampfnudeln? Because quite frankly when it’s my time to go I’m going to need you to bury me with a bunch of them. They’re my heaven.’

The women meander around the town, chatting and giggling and taking it in turns to exclaim, ‘I can’t believe this is happening!’ over and over as they pass the Perlach Tower and Augsburg Cathedral. After lunch they head to set, where Duke and Daphne are filming a George and Hermione kiss, after a build-up of half a book’s worth of tension on the will-they-won’t-they make it. After they get their passes and make their way to the designated area, they watch the scene unfold – first a rehearsal, and then a take.

‘When this is on TV one day, we’ll be able to say we saw it filmed live,’ Magda marvels in a whisper. ‘That’s so cool!’
