Martina Crowe is a cruel and self-centered student at the Institute. She works as a Messenger, helping Mr. Curtain transmit mind-controlling messages to the public with the help of his Whisperer machine. She takes pride in the status and privileges afforded by her position, and she takes an immediate dislike to Reynie and Sticky when they demonstrate their intelligence in class. Since the role of Messenger is given to the Institute’s top students, she perceives Reynie and Sticky as a threat and seeks to undermine them. When Sticky is caught cheating, he (at Reynie’s advice) lies to Mr. Curtain that Martina abused her Messenger status to coerce him to cheat. Rather than punish Martina for this, Mr. Curtain rewards her by promoting her to Executive.
