The Secret Friend

When Harvard student Emma Hale goes missing, her father fears the worst, and months later, her body is discovered in Boston Harbour. A year after Emma's death, another student, Judith Chen, disappears and is similarly found dead, prompting CSI Darby McCormick to take on the investigation. As Darby uncovers overlooked evidence, she unexpectedly connects with Malcolm Fletcher, a former profiler with a dangerous past, who may hold crucial information about the killer. With a third student missing, Darby finds herself ensnared in a perilous game of cat-and-mouse.
