Baker Georgia Tepper has been hired to provide delicious and spooky cupcakes for the Reading Buddies Halloween Party at the library, and she and Kathleen are meeting to finalise the menu of festive confections. Unfortunately, once Georgia's former mother-in-law ambushes her at the library and threatens Georgia with legal action, the afternoon of fun is soured. When Georgia's litigious ex-in-law is later found dead and the friendly baker is implicated, Kathleen is eager to help prove her innocence. Luckily, Kathleen and her intrepid magical cats, Hercules and Owen, have solved their fair share of mysteries. As a result, she knows that in life as well as in crime solving, it is all relative, but with hard work, she can make sure the right criminal is booked.
