Among my more exciting assignments of late was a day spent undercover with a team of private investigators looking into insurance claims. I learned how to spot a a surveillance team, how not to be seen, and how it’s slightly less glamorous than it looks on the telly. Oh, and how there’s much, much more of it than you’d think. Women make the best surveillance operatives I’m told – but you have to be prepared to sit still in the back of a white van for eight hours at a time. I’m not planning a career change.
