The fog settled thick over Blackwood Manor that cold evening. Detective Elena Marsh arrived precisely at half past midnight alone. Yellow police tape fluttered wildly outside the grand oak doors. Inside, Lord Harrington lay lifeless upon the Persian library rug. A shattered crystal glass glittered ominously beside his right hand. No footprints marked the dust except the victim's own trail. Every guest swore they heard nothing unusual during dinner service.
