The church bells rang thirteen times before anyone noticed blood. By dawn, the mayor lay beneath his locked study window. His shoes remained spotless, though the floorboards swam with blood. The key rested inside, beside a glass of warm milk. Detective Mara Voss arrived carrying coffee and yesterday’s folded newspaper. Across its front page, the mayor smiled beside his killer. Someone had carefully written KILLER across the smiling woman’s face. And the woman standing behind Mara wore that same smile. “He promised to die before telling anyone my real name.”
