Fablewood is a pretty dangerous place, but no area is more dangerous than the City of Rimes, deep in the heart of the Children's Realm. After transferring in from the realm of Mystery, a failed detective from an unfinished prose novel, Frankie Mack, is about to uncover a conspiracy that could unmake storytelling itself. After Humpty Dumpty is pushed to crack and Jack (of Jack and Jill) goes AWOL, Frankie and his partner, Simple Simon, are put on the case.
After throwing Humpty into custody for the murder of the Eastside Witch, the police precinct has all but closed the book on this case. Without the law on his side, Detective Frankie Mack must take the investigation into his own hands and find a way to end this growing turf war before there is no going back. Someone is looking to put this town in an early grave and it is up to Frankie to find out who before another key player bites the fairy dust.
