Sabrina and Daphne Grimm are ready to tackle their own case: Who is stealing the magical possessions of the most powerful Everafters in town? With Granny distracted by Mayor Heart's campaign against human residents, the girl detectives are on their own. Puss in Boots (now an exterminator), Cinderella (a radio relationship counselor), Sleeping Beauty (owner of a coffee shop), and their old enemy, Prince Charming, are among the many suspects, and one thing is for certain: The villain's plans mean a grim future for the Grimms—truly!
