I thought part of the issue was she started off being paid quite normally, then £1,000 a week for her exclusivity (still not an issue) but then he starting buying top of the range cars, land in Nigeria, cars for her boyfriend.
Clearly she should have smelt a rat by then and even if she did, she allowed her greed to overrun it. I'd certainly never accept a car or anything like that and who wants land in Nigeria?! She also flaunted it too much - is it any wonder her neighbours thought she was living beyond her means and got suspicious!
A think that's always niggled me with these things is, with all these luxury cars, who pays for the insurance?! That must cost a pretty penny itself!
