Rain tapped the foggy windowpane. A clock chimed midnight’s hollow echo. Shadows crept across the oak floor. A single candle flickered weakly nearby. Detective Gray rubbed his tired eyes. He sipped cold, bitter coffee slowly. The case file lay there open. A name stared back, underlined boldly: Eleanor Hart, vanished without a trace. Her photo smiled, hauntingly serene now. Gray sighed, leaning into his chair. His thoughts tangled like spiderwebs dense. Footsteps echoed faintly down the hallway. A knock startled him briefly awake. The door creaked open eerily wide. A shadow stood there, silent still. Gray’s hand reached for his revolver. “Detective,” the figure said, voice trembling. “She’s dead. They found her tonight.”
