Deidre approached the house that she knew to be Tristan Drage's tentatively; the man was a known death eater, and highly dangerous. He had succeeded in kidnapping his daughter from Hogwarts school itself, and there was no limit to what this man could be capable of.
All of the missing girls had been recovered, but it did not make any of the Death Eaters less criminal. As an auror, Deidre was obligated to hunt known Death Eaters down, and hopefully, would bring them to justice.
She entered the house, and found it to be empty, dust coating it with misuse. No one had been here for a long time. Armed with her wand, she made her way through the house, which albeit the dust was pretty clean.
A search proved fruitless, and nothing turned up except a few leather bound photo albums, filled with pictures of Tristan Drage and his family. Hopefully they would help in the hunt for him, and Deidre was unwilling to give up.
Frustrated at the turnout of the search, Deidre returned to the Ministry, planning to come back for further investigation.
