The old Victorian house stood completely silent against the bruised purple sky as the heavy rain began to fall tonight. Inside the grand foyer, Detective Inspector Mara Vance carefully examined the large crimson bloodstains now pooled on the marble floor. The victim lay sprawled beneath the ornate crystal chandelier, his expensive silk tie tightly twisted around his cold pale neck. Three suspects waited nervously in the library, each hiding their dark guilty secrets behind very polite and rehearsed alibis tonight. A single red rose lay crushed upon the ornate Persian rug right near the dead man's cold outstretched left hand. Mara knelt down carefully, her white gloved fingers hovering just above the mysterious symbol carved into the dark hardwood floor.
