Cute Or Terrifying

On the face of it this handwritten note on the neighbours window is cute and funny. Pop some movie horror music on it, add a little backstory, and this becomes a terrifying note just before the killings begin again!

Novel Cover

A novel's cover just waiting for the title.

I'm thinking Gothic adventure with an overwhelming sense of foreboding set in Victorian London circa 1891.

A golem may be involved.
