Nightmare Fuel / Going Postal

• The One Month Prologue, and the death of John Dearheart.
• The fates of the four previous postmasters:
  • Mr Mutable falls five stories 'smack, sir, smack on to the marble' head first, and splashes,
  • Mr Sideburn drops through the ghost of a staircase and falls down five flights of stairs, breaking just about every bone in his body in the process,
  • Mr Ignavia dies from a heart attack that, we later learn, was caused by walking through a human ghost and seeing everything inside them as he did it,
  • And as for poor Dark Clerk Whobblebury, who fell onto the "Bloody Stupid" Johnson-designed Sorting Engine... 'His head was all over the wall!'
• Mr Gryle is walking Nightmare Fuel. The wild banshee is not Played for Laughs and unnerves even Gilt's dedicated Igor, who has worked with werewolves and vampires before.
• The clacksmen's tendency to think they can fly, and learn otherwise.
• In-Universe, even, at least in the Sky 1 movie. After Pump tells him that "When banks lose money, it is not the banker who starves," Moist has a nightmare about the guy whose money he swindled hanging himself.
