My first reaction at the sight of Phin was one of surprise. No, thinking about it, surprise isn’t quite the right word. I was startled.

I’d known what he looked like, of course. It would have been hard not to when Anne had insisted that I sit through endless repeats of Into the Wild. It’s her flat, so she gets control of the remote.

If you’re one of the two per cent of the population fortunate enough never to have seen it, Phin Gibson takes ill-assorted groups of people to the more inhospitable places on the planet, where they have to complete some sort of task in the most appalling conditions. On camera.

According to Anne, it makes for compulsive viewing, but personally I’ve never been able to see the point of making people uncomfortable just for sake of it. I mean, what’s the point of hacking through a jungle when you can take a plane?

But don’t get me started on reality TV. That’s another thing I can’t bear.

So I was braced against the extraordinary blue eyes, the shaggy dark blond hair and the smile, but I hadn’t counted on how much bigger and more immediate Phin seemed in real life. Seeing him on the small screen gave no sense of the vivid impact of his presence.

I’m not sure I can explain it properly. You know that feeling when a gust of wind catches you unawares? When it swirls round you, sucking the air from your lungs and leaving you blinking and ruffled and invigorated? Well, that’s what it felt like the first time I laid eyes on Phin Gibson.

There was a kind of lazy grace about him as he leant there, watching me with amusement. So it wasn’t that he radiated energy. It was more that everything around him was energised by his presence. You could practically see the molecules buzzing in the air, and Phin himself seemed to be using up more than his fair share of oxygen in the room, which left me annoyingly short of breath.
