Over a period of six months, I uncovered up to 15 houses in and around Mayfair, learning how they operate.
All were some of the most exclusive addresses in the country, some even belonging to the property portfolio of the Anglican church, the London diocese fund.
In one of the houses, up to ten women sat in front of me and claimed to be Colombian, Italian, Portuguese when it was clear that they were mostly Romanian.
These women could be bought and sold for £300 an hour and served clientele that included famous premiership footballers, business tycoons and some prominent politicians.
