Early on in her career as a Death Eater, it was discovered that she had a gift for getting the reluctant to speak. Antonin's training had unlocked a set of skills she hadn't even known she possessed. Used a couple of times out in the field to the delight of the Dark Lord, a position was found for her within the Inner Circle. She was, of course, resented at first, but in time, most saw how valuable she could be to their regime. Eventually, she was ordered to devote her time to working with the Ministry to improve their own information gathering procedures. She was considered an expert in her field.
