The body lay motionless at the foot of the marble staircase. Blood stained the white carpet, spreading outward like crimson petals. Detective Morgan knelt beside the victim, her face grim yet calm. The grandfather clock in the hall chimed precisely three o'clock. Rain pelted the mansion windows as lightning illuminated the room. "Time of death appears to be around midnight," said Dr. Williams. The victim's hand still clutched a torn piece of paper. Lady Blackwood watched from the doorway, her expression utterly blank. "Everyone in this house is a suspect," Morgan announced firmly. The butler stepped forward, his gloved hands trembling ever slightly. "Sir Edmund had many enemies," he whispered, eyes downcast now. A silver cufflink gleamed beneath a nearby antique writing desk. Morgan photographed the scene while thunder crashed through the night.
