Just as magazines of the Warrior of Fortune persuasion are likely to be read by people leading humdrum and otherwise incident-free lives, or else by Nobby Nobbs, the readership of the Bugle is very likely to be drawn from people leading quiet well-ordered lives which are incident-free to the point of catatonia. A typical covert reader is Miss Drapes, a senior clerk at the Royal Bank of Ankh-Morpork.
