The cold rain hammered against the tall manor windows as Detective Sarah Chen stepped carefully over the broken glass shards. Lord Ashworth lay sprawled across the expensive Persian carpet, his pale eyes fixed forever on the ornate ceiling above him. A single white candle had burned down completely, leaving thick wax pools across the antique desk beside his lifeless body. The heavy study door showed no visible signs of forced entry, which meant the killer was likely someone he trusted. Chen knelt down beside the cold corpse, noting the strange expression frozen upon his pale face—half terror, half recognition. Whoever had poisoned his expensive evening brandy must have watched him slowly die, then calmly walked out into the darkness. The empty crystal glass still stood upright on the wooden desk, holding only a bitter residue at its very bottom. Six nervous guests remained upstairs in their rooms, each one claiming they had heard nothing unusual throughout the entire night. Detective Chen knew from her long experience that somebody inside this old house was lying through their perfect white teeth. Outside, the fierce storm intensified greatly, as if the angry heavens themselves were conspiring to keep everyone trapped here together.
