Heavy rain lashed the window. Thunder shook the dark mansion. Detective Miller entered the study. Lord Blackwood lay dead inside. Crimson blood stained the rug. A silver dagger gleamed nearby. The brass clock had stopped. Midnight marked his final hour. The wall safe stood open. Every priceless diamond was gone. Miller spotted muddy boot prints. They led toward heavy drapes. Shadows shifted behind velvet folds. Someone was still hiding here. Miller slowly drew his gun.
