Disappointment

I really wanted to include the picture book The Wolves in the Walls, but haven't found any basis in myth or legend, other than the idea of wolves being evil characters like in Little Red Riding Hood or The Three Little Pigs. As far as the origins of the story, Neil Gaiman has said (you'll have to click the tab that says Q&A with Neil, I tried to use Awesome Highlighter, but it wouldn't let me switch tabs) that the idea for the story came from the dreams his daughter, Maddy, had when she was little.

I have found it recommended for teaching philosophy for kids, but the story itself seems to be largely from the very unique mind and imagination of Gaiman, with little mythological influence.

I suppose the wolves have come out of the walls of this post, and it's all over for this search path.

I also seem to be having trouble finding information on the Sleer in The Graveyard Book. Most of the references I find are in relation to Gaiman's novel, however, there are drawings and game-related pages that make me think they are a mythical creature. At this point, I may just have to leave this one open-ended, and hope that I am able to come back to it and find more information. I updated my bookmarks with some of the references I found.
