The rain hammered the mansion windows as the butler discovered the dead lord by the fireplace in the cold night. His fingers still gripped a silver dagger, and its blade gleamed with fresh crimson blood beneath the dim gaslight beam. The door creaked, and three masked guests stepped in, each wearing a face of polite, careful calm that dark night. A clock struck midnight, and the hand of the dead lord moved, pointing at the window, then fell down slowly.
