Two Gaimans for the price of one.
I was originally going to read The Price for this square, but seeing as it's only a couple of pages long, I thought I should really read something else instead.
Poe's The Black Cat was the obvious choice, but I hate that one because of the cruelty.
Then I remembered the film version of Coraline had a black cat, and thought it would be nice to read the book it was based on. I found this edition which serendipitously enough, also includes The Price.
