Colonel Alice Panettierre is an army doctor introduced in Execution. She first appears under the guise of wanting to help Alex find Alfred Furnace, but in actuality also wants to recreate and use the nectar to build up her own army.
Panettierre is described as a woman in her forties, she has short graying blond hair and blue eyes. When first meeting Alex, she is dressed in a doctor's labcoat and wore Lucy's St. Christopher medallion before handing it over to Alex. Later in the book she wears army fatigues.
Upon meeting Alex, Panettierre is very patient and kind to Alex. He describes her voice as being soothing and oddly hypnotic. However, the more that Alex continued unable to give her the answers she wants, her patience wears away quickly and becomes much more cold and aggressive in her questioning. When her true intentions are uncovered, its abundantly clear how much of a sadistic, power hungry butcher that she is. When Alex spares her and escapes, she vows to find him again and relentlessly pursues him and his friends.
