Do not call me Siobhan. This means you, Ron. Call me Elizabeth. Liz, or Lizzie, if you so desire. But not Siobhan.
You probably know me. Even if you don't recognize me or know what my name is. This is because I'm the top undercover auror at the Department of Magical Law Enforcement. If only because I always, always manage to sleep with the people who have the information we need.
