Here she offers her tips on how to track down elusive characters like Bernard Tapie.

Telephone: The phone is your biggest source. Call information and if you can't get through with information go to Google.

Internet: Try to get to them through someone else. Look the person up and see if there's anyone they're in business with. Once you get the number just try calling at different times and always be really charming on the phone.

Persistence: I could have dropped the Tapie thing at a certain point. Either you're a person who gives up, or you're a person who doesn't. And if you're a person who doesn't then you've got a greater chance in succeding.
