Detectives Carla McBride and Bernie Kowalski join forces with Beth Pendergast again in a test against their patience and experience when a twenty-year-old cold case is brought to the forefront. All hands on-deck, a major curveball is thrown their way that takes the investigation well beyond their beloved Oakmont community. And legendary Detective Ace Hutchinson-who was the original lead investigator on the case-becomes a major player. Only thing is...nobody is sure whose side he is on. Standing in the way of closing this decades-old cold case are a multitude of suspects, persons of interest, and unexplained reasons complicating an already-perplexing investigation.
