My sense is that she didn't make the transition from walkup to ordinary in-call work that well. These two ways of working are quite different and demand entirely different kinds of preparation, attitude, engagement, organisation, etc. I remember the famed Renata (terrific fuck!) of the 2 Greens Court walkup telling me that in terms that I found quite convincing. She started in a walkup, left Soho to do ordinary in-calls somewhere in NW London, and then returned to Soho.
