A successful film professor and podcaster, Bodie Kane is content to forget her past--the family tragedy that marred her adolescence, her four largely miserable years at a New Hampshire boarding school, and the murder of her former roommate, Thalia Keith, in the spring of their senior year. Though the circumstances surrounding Thalia's death and the conviction of the school's athletic trainer, Omar Evans, are hotly debated online, Bodie prefers--needs--to let sleeping dogs lie. But when the Granby School invites her back to teach a course, Bodie is inexorably drawn to the case and its increasingly apparent claws. In their rush to convict Omar, did the school and the police overlook other suspects? Is the real killer still out there? As she falls down the very rabbit hole she was so determined to avoid, Bodie begins to wonder if she wasn't as much of an outsider at Granby as she'd thought--if, perhaps, back in 1995, she knew something that might have held the key to solving the case.
