Someone stole the key to the Black Cat Bookstore! Lucky for the store's owner, Mr. Brown, his clever cat, Cobweb, is on the case. Cobweb has a plan to scare the burglar away, and the ghost who lives in the bookstore is happy to help. There's only one problem-the burglar doesn't believe in ghosts. But maybe he'll change his mind once he meets the special ghost who lives in the Black Cat Bookstore.
