Nathaniel Browne's Secrets
From Tatters of the King
Nathaniel's friend, Jean-Paul Etienne, is a user and supplier of certain mind-expanding substances (including opium). Nathaniel has partaken of these on occassion.
Nathaniel does not, as he appears to, live off any inheritance. In fact his parents left him very little. Instead he writes gossip columns for a London paper under a pseudonym (John Parker). He sends his stories to the newspaper's editor, George Baker, and recives payments via a post-office box.
