Well would you do it? Could you back-stab somebody for the chance of winning a chest full of treasure?

It became obvious that this was one of the requirements after I hot footed it to the smoke for my screen test. I made it clear I could not do anything that compromised my integrity, that I would try and find another solution, even if it meant losing out on a £50,000 prize.

I must also admit that I stumbled badly when it came to the lateral thinking test and I was faced with a row of figures which I had to complete. Maths never was, or ever will be, my strong point (thank heavens for calculators, I say). The pic shows me and others filling in the paper work.

It was great fun flirting with the thought of fame and fortune, and I’m very grateful to the Tory top guns who recommended me to Princess Productions as an intrepid, “strong woman” able to take on this challenge.

They had 7,000-8,000 applicants for The Search, Indiana Jones crossed with The Da Vinci Code, whereby 10 bright minds take off around the world solving codes and facing challenges to bring them closer to the treasure.

It will take them to stunning archaeological sites not normally accessible to the public, it is the trip of the lifetime that money cannot buy.

The final five men and women had been selected, and had even spent a bonding weekend in a hotel, but it was still felt that another “strong” woman was needed, hence my last minute invitation as the team sets off in about three weeks.

I have a friend who makes documentaries and she told me they would be looking for someone “combative”, which is not my nature. I’m sure my lack of skills with maths could have created considerable problems too – just imagine if I was faced with the treasure chest and had to unravel a complicated code of figures to open it, I could never do it, it would remain locked forever.

So what would you have said in my shoes, could you back-stab somebody for fame and fortune?
