Allison Taylor is having some trust issues, when a woman from Mark Ryan’s past turns up in Spring Hollow, and makes it very clear she’d like to revisit old times. And Elizabeth Meade is writing a murder mystery. But then people start dying just like the characters in her book, and it seems likely the killer is someone Lizzie knows. Mark Ryan would like Ally to leave the police work to him, but Ally, Lizzie, and new friend, Larry Jones, decide to investigate before someone else winds up with a knife in their chest.
