Cold rain lashed the windows. Thunder shook the dark mansion. Detective Miller entered the study. Arthur Vance lay dead inside. Fresh blood stained the carpet. A silver dagger gleamed brightly. Broken glass covered the floor. The heavy safe stood open. Priceless jewels were completely missing. Six nervous guests waited below. Every suspect hid a secret. No guest spoke the truth. Shadows danced across the walls. Miller opened his leather journal. The killer was still here.
