But the minute I met them, I felt welcome. Sometimes I marvelled at how quickly they’d accepted me. Almost like they had been waiting … and there I was.

Anya told me about her sister, Isabella, who had died of an infection when she was a few days old and whose solo picture – a small, red face in a white blanket – sat among all the ones of the sister who lived. Anya confessed that she felt guilty for having no feelings about this stranger at all and I could understand it, a little. But I think it was one of the reasons they were all so close, as a family. They were grateful for what they had, and maybe conscious that it could be taken away in a few failed breaths.

I was a bit taken aback that Anya was really called Anastasia. Julia only brought that out to wind her up though, as she hated that name. As a tiny girl they had called her ‘Stasi’, but it was a little too East German Torture Squad when written down, so it morphed into Anya, which she used as her official name now.

Patrick was a barrel of man with a hearty laugh and a propensity to see the positive in everything. He came from working-class roots, growing up in Liverpool and going on to work in shipping. Sometimes he made a comment about me and him having things in common, but we didn’t, not really. Very occasionally, you would witness him on the phone dealing with someone difficult and there would be the smallest flash of something else – something sharp-edged that was swaddled by his comfortable home life. He liked to go hunting now and then in Scotland, and I was grateful he never felt the need to ask me along for a father-son-in-law bonding session over dead, furry animals. Not my thing, in any lifetime.

Julia worked in publishing as a literary agent and was lively, fun company. She tended to clasp me in perfumed hugs and say things like, ‘Darling, how is my most favourite son-in-law?’ as though there were competition for the title.

That’s not to say that I hadn’t found her intimidating when I’d first met her. She’d peered at me over her glasses with a slight frown and, for the first half hour in her company, I’d felt a little like I was under a microscope. Then she’d seemed to change, just like that, and was warm and welcoming. I never really knew what it was that turned her around. Maybe she just saw how I felt about her daughter and approved of the sea of love that was on offer.

Anya was their everything. That was clear to anyone who knew them. She was the golden child – the one who survived – and they would do anything to protect her.
