The old manor loomed beneath a bruised and swollen sky. Detective Mara Lane stepped from her car onto wet gravel. She counted three chimneys, but only one thin plume rose. A constable waited by the iron gate with a lantern. "Evening, ma'am," he said, voice tight as old piano wire. "The body is in the library, as the call said." Mara nodded once and tugged her collar against the chill. Inside, the foyer smelled of beeswax, rain, and old secrets. A grandfather clock ticked loudly, then stopped at ten thirteen. She glanced at the marble floor and saw one pearl. It lay by the library door, its surface smeared red. She knelt but did not touch it, letting silence settle. Someone had moved through this house with terrible, practiced calm. "Who found him?" she asked, her voice low and even. The constable pointed toward a slim woman in black velvet. "She is the victim's sister and reported a loud crash." The woman did not weep; she stared at the fire. Mara studied her hands, her hem, and one scratched wrist. "Show me the room," Mara said, stepping toward the library. The constable exhaled slowly, then turned the heavy brass handle.
