Here's a turn up for the books:
I told Rachel that I sent her money and asked why she needed tickets...
It is a small gathering, the tickets are so I know that the people are serious and a select few can come, I have the parties every month, Xxx xxxxxxx, North Kensington, London, Xxx, once I get home I will send you a ticket to show the person at the door and they will let you in.
The address omitted a door number and last few digits of post code. She'll flip when she sees I've not sent her money.
Google map shows address as a respectable housing estate.
More advice please...
