Let& #39;s say, THEORETICALLY, there& #39;s a fic in which a character appears to be a ghost haunting a house. From the beginning. The tags are: MCD, ghost character.

if neither MCD nor ghosts are tagged, a reader will likely read the first chapter and think, huh. There are no death and ghosts in the tags, so something else must be at play here (the character is in a coma, or in a parallel dimension- but not dead) that will be revealed later.
