Ten interconnected cases. One devastating revelation. Dr. Claire Morrison makes her living inside the minds of killers. Fighting to stay sober and haunted by her mother's disappearance, she's built her career profiling Baltimore's most dangerous criminals. But nothing prepared her for what's coming. A mathematician who outlines victims with equations. A killer obsessed with mirrors, staging terrifying final reflections. Two murderers working in perfect, deadly symmetry. As Claire and her partner, Detective Sara Martinez, hunt these predators, a disturbing pattern emerges: someone has been watching her work, studying her methods, manipulating some of her cases from the shadows. Her past is catching up... Her demons are closing in... And among all these calculating minds... The most dangerous one knows her better than she knows herself. Some truths destroy lives. Others end them.
