It occurred to her when she passed the front door that if Draco truly had plans to turn her over to someone else who might not have her best interests at heart, he would ensure that she couldn't actually leave his refuge. He would look terribly foolish if he announced that he had her stashed away in a safe place only to discover when he brought the interested party over to see her that she escaped. Cautiously feeling around the front door for any hints of unusual security wards, she found nothing out of the ordinary. Years as Antonin's student and then even more years as a wife provided her the opportunity to learn a great deal about wards. Her husband had been a cursebreaker for Gringotts straight after leaving Hogwarts. If the money had been better and he hadn't been forced to leave the country for long stretches of time, he might have continued in that same profession. Once he was recruited by their mutual master, he was needed in a position that allowed him to be closer to home at all times in case his particular brand of expertise was required by Lord Voldemort.
