Cold wind howled through the desolate, dusty mansion. A crimson tide spread on the antique rug. Lady Eleanor lay still, her life now gone. Her vacant eyes stared at the ceiling lamp. No obvious weapon lay within the immediate vicinity. The grand clock chimed a mournful twelve o'clock. Shadows danced wildly across the cavernous empty room. A broken teacup lay shattered near her pale hand. Something truly sinister had occurred in here. The air felt heavy with untold secrets. A creeping dread settled upon the entire estate. Justice would demand answers from this silent witness.
