The body lay still there. Blood stained the marble floor. Detective Miller entered the room. He observed the pale victim. A knife protruded from chest. "Who found this poor soul?" The butler stepped forward slowly. "I discovered her this morning." Miller knelt beside the corpse. Cold air filled the chamber. Candles flickered on the mantle. Something felt terribly wrong here. Evidence suggested a violent struggle. Broken glass littered the carpet. A window stood wide open. Footprints marked the wet grass. The killer had escaped outside. But why leave the weapon? Miller pondered this strange detail. Perhaps the murderer knew something. Or maybe panic caused haste. He touched the cooling skin. Rigor had not set yet. Time of death was recent. Within two hours, perhaps less. Miller stood up straight now. "Secure the entire perimeter immediately." He turned toward the doorway. Shadows moved in the hall. Everyone here was a suspect.
