The daughter of an ex-army intelligence officer, Mary is quickly moving up the CSIS ladder with a recent promotion to temporary head of the Asia Pacific Region. Having past experience as an undercover operator as well as a handler, and having worked around the globe from Panama to Australia, Mary is to all appearances hungry, ambitious, and egotistical, but with the brilliance to back it up. Even so, her drive to rise in the spy service can cause her to overreach her control. Beneath her well-armored exterior, she is a lonely soul, but having been betrayed by an adulterous husband, she is guarded about entering into any new loving relationships. Forever an outsider, her own ambitious nature has a tendency to get the better of her. Manipulative and extremely charming, Mary constructs herself as a powerful intelligence chieftain. Fueled by a need to control her environment, she rules her domain with swift discipline and, if needed, reprisal.
