Effing Forest

This is a scenic location presumably in the Greater Ankh-Morpork area, which serves as both a scenic beauty spot and a euphemism. The wood from its trees, by all accounts, makes superior furniture and interior building structures, allowing Sir Harry King to threaten to throw somebody down these Effing stairs without any actual use of profanity. Sir Harry is thus enabled to perform a meaningful act of violence without sullying the ears of Lady Effie. Perhaps an, er, Hellstree exists in the forest.
