Monkey Street is in the Shades of Ankh-Morpork. It runs fron the docks into a maze of twisting and turning alleys that eventually resolve themselves on Shamlegger Street. This is not a nice place to be lost in without a local guide.
Renowned, or at least notorious, for premises used as the "registered address" (or at least somewhere for the postman to deliver lots of gullible peoples' money) for lots of businesses which have C.M.O.T. Dibbler as a common theme..
