The Widow was the most feared assassin in all of the noble world. No one ever knew who she was to strike next. Sneakier than a fox, quieter than a mouse, and faster than a cheetah. When her next mission is to become a maid for a well known Earl with an amazing butler, will she be able to kill them, or will something she doesn't believe is real happen to her? I do not own Black Butler. Originally posted on Quotev on 4/21/2013

Sebastian and Ciel's relationship has changed after their contract ended. Ciel is no longer serving the queen but, like always he's managing his business under Sebastian's supervision. I don't know how to summarize it so I'll stop there. You can't judge a fanfic by it's description, though it gives you an idea on how screwed up it's going to be.

"Ha. So the old man's got a family, how sad! They'll see him die soon enough." You whispered as you grabbed 4 throwing knives for each hand. You positioned them and made your arms form an X, and you threw. Closing your eyes, you sighed and awaited the screams that would follow. "My, my, my. What do we have here? An assassin perhaps?" A deep British voice pondered. Dang. You had been caught by someone. Before you turned around you saw the family of the criminal move inside the house. Dammit! Your knives missed him? What? You finally turned around to look at a man with brownish reddish eyes, his black hair blown lightly by the wind, and in his white gloves... were your knives. You stared at him in bewilder. "How did you catch my knives? I didn't feel the wind from you at all! Why did you save him? He deserved to die!" You exclaimed angrily. He just laughed and answered. "Would you care to join us at the Phantomhive manor?" Enjoy~
