The heavy rain drummed against the cold and dark window. Arthur entered the room with a trembling and pale face. A silver dagger rested deep inside the velvet parlor chair. The body lay still upon the thick and crimson carpet. Silence filled the hallway while the clock struck midnight once. He reached out to touch the victim with shaking hands. This night would change the lives of everyone inside here.
