Rain tapped the tall windows of Blackthorn Manor while eleven guests waited in the candlelit drawing room for their host. At precisely nine o'clock, the butler opened the heavy oak doors and announced that dinner was finally ready upstairs tonight. No one noticed the eighth place setting until Lady Evelyn pointed toward the polished table with a trembling gloved finger. The guests climbed the grand staircase slowly, whispering about the absent host and the strange extra chair beside the fireplace. When the doors opened, Lord Harcourt sat slumped in the head chair with a silver knife deep in his chest. Lady Evelyn screamed once, then pressed her handkerchief to her mouth while the butler checked the dead man's cold wrist. Every guest stood frozen near the doorway, and every eye turned toward the empty fourteenth seat at the far end. Detective Mira Vale arrived twelve minutes later, brushing rain from her coat and studying the silent, frightened faces before her. She asked who saw Lord Harcourt last, but no one spoke until a clock chimed softly somewhere below the stairs. Mira lifted the dead man's napkin and found one chilling message written in red ink: "Fourteen will dine no more."
