The old mansion loomed silent beneath a bruised night sky. Rain tapped softly on the dusty windows of the library. Inside, a dying fire crackled in the wide marble hearth. Six guests sat in an uneasy circle near the flames. At the head of the long table sat Lord Blackwood. His eyes were closed, his face as pale as paper. A crystal glass lay shattered on the polished wooden floor. Red wine spread beneath his chair like a dark warning. No one spoke as the loud mantel clock chimed midnight. The distant storm outside echoed the tension within the room. Detective Eleanor Vance stepped through the heavy oak front doors. Her sharp eyes swept over the shaken group of suspects. "Lord Blackwood is dead," she said in a calm voice. A woman gasped, and someone knocked over a silver candlestick. The storm raged on as the long investigation finally began. Outside, distant thunder crashed across the dark, empty, windswept moor. One of them was a killer, and morning felt distant.
