I know what she eats, which must-have brands she applies to her face, and the price of each carefully selected 'piece' in her multi-million-pound home in Belgravia.
Because Ris, as she is known to her many followers, likes to share.
And now I'm here, in her home, watching her every move.
Entrusted with her secrets and running her diary from the bijou basement flat, I'm on hand to fulfil Ris' every need. Her right-hand woman. But what she doesn't know is why I'm really here.
I've put a lot on the line to get this job, and now my plan can begin.
I've waited long enough.
