Model response

The storm raged outside the old, crumbling manor tonight. Inside, the butler found the body in the library. Blood pooled beneath the lord’s ornate, velvet chair. The clock on the mantel struck twelve, ominous. A single, red rose lay beside the corpse. No signs of forced entry were ever found. The detective arrived, her coat still soaking wet. She surveyed the room, her eyes missing nothing. The widow screamed, a performance for the audience. Everyone gathered, each with a hidden, guilty secret.
