If I’ve seen him once, I’ve seen him a million times. After four years of working in the merciless City, sharing everything from trading tips to cocktails with my male colleagues, I have a highly developed nose for that toxic breed of banker who can have any girl he wants: the player.

You know the type. Not only do they lie and cheat with the insouciance of the seasoned adulterer, they even maintain several mobiles to run their several lives (having pulled someone or other by pretending to be an architect or a film producer, depending on the demographic at the bar). And so it is my golden rule to never, under any circumstances, sleep with someone from work. I can proudly say that no amount of sweet-talking would ever lure me into any player’s honey trap.

Except one. He was a gorgeous Scandinavian who started on the same graduate scheme. Although we worked on separate teams, we were exceedingly competitive and this gradually morphed into a flirtation. As smooth as Bill Clinton, he looked great, was multilingual and ticked all the other relevant boxes too. One flicker of his crystal blue eyes and I forgot where I was or what I was saying. It was that bad.

And then the most amazing thing happened: he announced he was quitting! I realised then and there that this was God’s “green light”. So, after his leaving do at The Fine Line, I held my breath and pounced – grabbing his tie under the Monument and kissing him at the same spot so many other girls had before me. It isn’t sleeping where I work when tomorrow is his last day. But the next morning, that green light began to turn an ugly shade of red.

My exceptional crush was SO amazing and SO good at his job that the powers-that-be had pulled out the big guns and sat him down to “reconsider”. When he emerged from that meeting room, beaming all over his beautiful face, I realised with horror he was staying. The head of fixed income had complained he had trained a “Jedi warrior to be a black belt who was quitting at green”.

The moral of all this is: if you fancy someone in the office, make sure that when you finally do mix work and players, do so only after he has, unquestionably, turned in his security pass.
