There was a documentary on television earlier this year with Rupert Everett and he visited an agency in the north east run from a small town in co. Durham I think. He interviewed the owner, a woman. Do amour and diamonds have their offices in Newcastle?
Don't know where there offices are but I doubt they would be doing it Diamonds uses flats where more then one girls work, amour say they don't operate brothels but it has been known that some of the girls that work there have shared flats.
Plus they pretend to be escort agencies but both agencies operate mainly incalls at £50 and most jobs seem to be 30 min incalls so not much escorting going on.
Prestige and Valentines are more escort agencies as they mainly send girls out to punters and don't do 30 minute appointments.
Amour and diamonds would be better changing the escort thing to mainly massage girls or something along those lines would represent them better.
And I doubt the chest sitter would be involved as he already seems like he is on the police radar with all his activities so doubt he would want to appear plus he has all the girls operating and sitting around the flat/brothel
