A shattered vase and spilled wine marked the chaotic scene, hinting at a struggle that ended in tragedy abruptly. Moonlight filtered through cracked blinds, casting eerie shadows across the bloodstained carpet and trembling victim’s outstretched hand. Detective Harris knelt beside the body, searching for clues while his mind raced to piece together possible motives. A cryptic note clutched tightly in the victim’s fist read: “Secrets buried must never be uncovered or else consequences follow.”
