The night was dark, silent. Rain fell hard upon rooftops. Shadows lurked in every corner. A scream pierced through the gloom. Detective Gray arrived at scene. Victim lay sprawled on floor. Blood stained the antique carpet. Guests gathered, whispering in fear. No one seemed quite innocent. Secrets hid behind every smile. Gray’s eyes scanned the room. Clues waited to be uncovered. The mystery had just begun.
