"Alright, Amelia", Dumbledore was saying, "Let me see if I have the right of this. You have, over the past two days, arrested a large fraction of the wizengamot, the minister, his undersecretary, and quite a few marked death eaters?"
Amelia nodded. "You have the right of it."
Dumbledore sighed. "What triggered this?"
"The arrest of Barty Crouch. Did you know that there are no records of any interrogations of any marked death eaters, anywhere? Certainly none happened on my watch, but as near as I can tell, none happened before, as well. They very well might have, but there are no records of it. After I interrogated Crouch, I discovered that death eaters cannot be forced into taking a mark."
"Right, I recall you sending me memories of that interview."
"Well, that led me to Fudge, and I was able to nail him for accepting bribes. That led me to Umbridge and Malfoy, and let me tell you, Malfoy was the mother lode! Did you know he watches "Jerry Springer"?
Dumbledore shook his head gravely. "I was hoping that he had not fallen that far into the dark."
