Wicked- a Bastille and Harry Potter fanfic

~Silhouette~

Throwback
A cold winter, dark and cold. Not a single person shows himself on the street, although...... There's a silhouette on the horizon, a human in a thick black coat. In a discrete tread he walks to a house, and he knocks on the door. It's a strange family living there. They all wear the same awful dresses and hats, and they always seem to have a branch with them. They never get visitors- not through the front door at least- so this is peculiar. Not that long after that the silhouette comes out, taking the woman and daughter with him and leaving the man behind. He became crazy after that, visited therapist after therapist. A few years later I saw the silhouette again, but this time I could hear what they said: "Give me your nephew Dan Smith, and I'll give you your wife and daughter back." And now his little brother is in the house. He came in with a teenage boy, but I never saw him come out. Is this that Dan Smith? Is this the guy James has to bring to the silhouette?
