The rain fell hard on the old Victorian mansion's roof. Detective Sarah Chen stood within that dark and muddy garden. She stared at the broken window on the second floor. Someone had killed the wealthy owner inside that room tonight. Blood stained the white carpet near the mahogany desk heavily. A single red rose lay on the victim's cold chest. The butler waited nervously in the hall below them silently. Sarah pulled her coat tighter against the freezing night air. Three suspects were already gathering in the grand dining room. The storm outside rattled every window in the old house.
