Detective Marlow arrived at the old Harrington estate just as thick fog rolled slowly across the manicured lawn that evening. Inside the grand foyer, a body lay beneath the crystal chandelier, dressed in a velvet gown soaked with dark blood. The elderly butler claimed he had heard a single gunshot echo through the silent halls shortly after midnight last night. Marlow knelt beside the victim and noticed a torn photograph clutched tightly in her cold, pale, elegantly manicured hand. Nobody in the entire house would admit to seeing anything strange, though every single servant seemed strangely nervous about something. Outside, rain began to fall against the tall dark windows, and Marlow quietly wondered who among these guests was lying.
