Hard Justice

When a biotech executive is found murdered in Boston with a cryptic neurological imprint left at the scene, homicide Detective Sean Malone is pulled into a case that doesn't behave like any he's seen before.Partnered with Detective Sarah O'Connor—Internal Affairs' sharpest observer and his least trusted ally—Malone traces a series of killings to OPUS, a defunct neuroscience program that once experimented on human cognition.But OPUS never truly ended.As more bodies surface, Malone uncovers a hidden network linking City Hall, the police union, and a covert program that may have produced something far more dangerous than a weapon: a survivor with a fractured mind and a kill list written in memory itself.The deeper Malone digs, the more the case stops feeling like an investigation—and starts feeling like containment.And someone in power is willing to burn the entire city to keep OPUS buried.Perfect for fans of Dennis Lehane, Michael Connelly, and Tana French.
