"The Dark Lord had Ollivander brought here a year ago whilst he sought to learn the location of the Elder Wand.  Ms. Lovegood was only brought here recently.  She has not been mistreated.  Though I am unclear why he had her brought to us, I believe it was in response to her father’s support at his rubbish newspaper of your friend Mr. Potter.  They are... relatively... safe in our care, so long as the Dark Lord has no further information, he requires of them."
