This is just a brief one, but…

I’ve been reading A Lesson in Vengeance, been part way through it for a while. The combination of that book, plus my own meditations, has left me musing on the nature of ghosts and how they work in stories. I don’t think I’m saying anything revolutionary when I say that, while ghosts are often said to have unfinished business, they can also be interpreted as the unfinished business of those they haunt.

Ghosts make a neat device for unwelcome and intrusive thoughts.
