1. Snooty assistant in the ship shop who’d played the role one too many times and now her face was stuck like that
2. Room steward Amanda who always seems to be outside my cabin door ready to clean. The most ubiquitous woman since the Fiji Water Girl
3. Meghan Markle’s sister
4. Man on the harbourside who threw a plastic bottle into the ocean
5. People who have no personalities outside of their relationships with their spouses – e.g. Bardot and Gareth. Also…

I’d found Beatrice on the morning of the Mallorca trip while I was googling sex offenders. In between waiting for pages to load and checking my niece Mabli’s latest vlog about her new micro pig and finding Twitter posts about paedophiles I knew would trigger me – I do that sometimes – I’d absent-mindedly put the words ‘Beatrice’ and ‘Capri’ into the search bar.

Caro had mentioned Beatrice’s maiden name was Genovesi so I started there. There was a jewellery store on Capri called Genovesi which had changed hands in the Seventies but the owners had kept the name. Beatrice’s father had sculpted cameo jewellery and though he was long dead, I followed that line of inquiry and Google Translated a message to the current owners asking for any information. They got back to me later that afternoon.

Beatrice and her husband Rocco had sold the store in the Seventies and moved to the outskirts of Rome. Taissa had told me their married name was Pelagatti – a thankfully rare surname – and that was where her knowledge went cold. I widened my search for Pelagattis in or near Rome and sent several people with the surname the same message.

I’d all but forgotten about it, until the morning we docked in Barcelona and a notification pinged through on the cracked iPhone. My heart skipped a beat, thinking it was from Dannielle Fairly, but it was a guy called Enzo Pelagatti. He’d contacted me in English, saying he was a student in Rome and that his grandmother had been called Beatrice Genovesi in the Fifties. He’d spoken to her and she remembered Caro and would love to see her again.

His actual words were: ‘Beatrice vuole vedere il suo amato Caro più di ogni altra cosa al mondo.’ Or rather, ‘Beatrice wants to see her beloved Caro more than anything in the world.’

So I set up a meeting for when the ship docked in Rome. A little knowledge and a search engine goes a long way these days so it was piss-easy all in all, but Caro was acting like I’d scaled Everest and found Beatrice resting on the south-east ridge. All the way back to the ship she cried.

‘I can’t believe you found her. I can’t believe I will see her again. You are a wonderful person, Hilary, truly wonderful.’
