Fog enveloped the quiet town. Moonlight pierced through dense trees. A shadow moved near mansion. Eerie silence gripped the air. Butler discovered body in library. Blood stained the ornate rug. Victim clutched a cryptic note. Clock struck midnight with dread. Suspects gathered in dim hall. Secrets whispered among the guests. Detective arrived with keen eyes. Mystery unfolded in hushed tones.
