Thick fog rolled over the cobblestone street as Inspector Vance pulled his heavy wool coat tightly against the biting wind. Yellow police tape fluttered wildly outside the grand manor house where a famous millionaire lay dead inside his quiet study. A shattered glass of expensive vintage wine sat beside the body, its dark liquid staining the pristine white velvet carpet. Vance knelt beside the cold corpse and immediately noticed a silver pocket watch clutched tightly within the dead man's fist. Nobody had entered or left the estate grounds all evening, meaning the killer was still hiding somewhere inside this mansion.
