But, after a few minutes, and much to my surprise, I start to enjoy his company immensely. He says women in New York are only interested in how much money a man makes. But I can tell he fancies me, this despite his lack of curiosity about me, and his disconcerting habit of continuing to talk into the remote of his mobile phone. Men like to know they come first.' After two hours, he pays for our drinks, apologising that he has to leave for a dinner engagement.Don't you fancy the over-groomed, immaculate Manhattan type? He keeps touching my arm and once, instead of saying, 'If I were to have a relationship with you', he says, 'If I were to have sex with you'. He is put off, though, when I tell him about my animals; particularly my anecdote about the fact I've trained my three lambs to kiss me on the mouth. He gives me his card, and asks me to ring him if I'm ever in New York again.

I hobble off into the night on my shoes and text Mairead: 'Am V depressed. I find this hard to believe, having watched a great many episodes of Sex And The City, but I valiantly call skirt and shoes into service yet again (wearing the same outfit acts, I as a sort of scientific control), meet Christie, from Mairead's sister agency, Premier Matchmaking, who is hand to arrange everything.

Our chat reveals straight away how different the dating scene is in the U. She tells me where my prospective date went to school and college, lists his many degrees, tells me he is 6ft 2in, divrced with no children, and is the CEO of a bank. I agree to meet P at a restaurant on Madison Avenue. He arrives, and although he is indeed tall and dark, resembling none other than Mr Big, I know in less than five seconds that I will never fancy him. The test is what they look like straight out of the shower.' Oh dear.

We say our goodbyes and I go to freeze in the snow, trying to hail a cab.

After about ten minutes, a man asks if I need help.

Otherwise, the qualities I am looking for are pretty standard: he must be kind, funny, not pompous or bossy, be intelligent and well read and an animal lover.

I tell her I'd prefer someone around my own age (she tells me I don't look 50, and am in fact 'slim, fashionable and gorgeous', which makes me want to date her), but they must be boyish rather than Steptoe-like (I tell her Imran Khan could be her template, although I wouldn't date him as I don't think my cats would want to live in Pakistan).I feel as though I'm about to sit my A-levels all over again. Mairead phones to tell me about M, who is 46, in wealth management, whatever that is, and a divorced father of two grown-up boys. We agree to meet the following night in the bar at Claridges. I buy a black lace skirt and silver platforms from Prada, and get my hair done.I tell him I have dark hair, and will be wearing purple Burberry platforms. I invest in a Hollywood wax, and an all-over light sheen of fake tan.With such a terrible track record, I started to realise that, if I couldn't meet someone when I was in my prime, how on earth was I going to meet someone now I'm 50?My friend Kerry, tired of my moaning, had told me about an upmarket dating agency that takes on only high-achieving rich people.Berkeley International's membership fee of £6,000 per year guarantees her clients - hundreds of singletons from all over the world, at a ratio of 50/50 men and women - are solvent, but I'm surprised when she tells me how many are multi-millionaires.
