Every member of Rainbow Bridge is known as a Trans-Actor.
Simon and Zoë work in different capacities there. Zoë is one of the practitioners.
Simon is general messenger man.
Rainbow Bridge is such a dysfunctional institution, even its sign- board outside is mis-spelt. For this reason, it is referred to as Raibnow B.idg in the pages of the book.
Symbolically, at Raibnow B.idg, all the accumulated knowledge of self-discovery: workshops, courses and findings-out are to be found in the pigeon-holes in the Trans-Actors’ room.
