The thick coastal fog completely enveloped the old Victorian mansion on the hill that night during the terrible storm now. Inside the grand ballroom, elegantly dressed guests danced gaily as a large clock struck twelve times exactly that cold evening. Suddenly, the music stopped completely and then a woman's terrified scream echoed from the upstairs study room quite loudly now. The guests all rushed to the study quickly and found their host dead on the floor coldly still right now. A single silver letter opener lay beside the body and a note was clutched tightly in his hand now too.
