Mr Salzella
The Director of Music at the Ankh-Morpork Opera House in Maskerade, most notable for an absolute hatred of opera. He embezzles money and murders the people who find out, blaming the murders on the Opera Ghost.
Salzella is eventually found out and proves to be just as "infected" with operatic romanticism as everyone else in the building. Due to the Discworld's rather literal adherence to the laws of narrative convention, this is not an entirely mental issue: He is killed in an extremely operatic duel with the Ghost and spends two pages on a final monologue before keeling over. He only had a sword theatrically thrust under his armpit, but according to the witches present, failed to notice this.
