There was some truth to the matter that if anyone inside the regime was able to help facilitate his escape, it would be Hermione. In her former position as Co-Head of the Ministry's Intelligence Department, she had access to every single person wanted for questioning by an official working with the Ministry. Didn't matter which department brought them in, she was able to speak to them by doing nothing more than simply entering a room. Everyone knew who Hermione Dolohov was. Even if they weren't aware of who she'd been before the war ended, they knew the position of power she held. No one would keep her away when she wanted something. All it took was one word from her and their entire family could be snatched up and dragged to their own cells. It was enough of a discouragement to stay out of her way.
