Hermes the Literary Agency (Susan Wells)

Hi,
firstly this a copy of my query in the 'newbie' thread and thanks to Ben Bradley for suggesting i post here.

Does anyone have a contact for Susan Wells of 'Hermes the agency'?
I have lost contact, the last address I have is Datchet, Berkshire, UK, but that was at least 7 years ago.
thanks
crispy

that's it,
I have tried phoning but it seems the occupancy has changed a number of times since Susan Wells lived there.
