Jean Underwood
Jean Underwood is the Algebra II teacher at Placerville High School whose murder by a single gunshot to the head at the hands of student Charles Decker ignites the hostage crisis that forms the central action of the novel. A stern, mocking pedagogue who wields her authority with a shark-like smile and a cutting tongue, she is killed in the opening seconds of the rampage, becoming the first victim and the catalyst for the day's violence. Her death, and the students' muted reaction to it, establishes the novel's central themes of suppressed rage, the failure of institutional authority, and the thin line between civilized order and chaos.
Identity and Classroom Persona
Mrs. Underwood is a middle-aged teacher who carries two tartan-patterned plastic briefcases to each class, earning her the nicknames "Book Bags" and "Two-Gun Sue" from her students. She wears harlequin glasses and favors a casual tartan coat over a brown cashmere sweater. Her teaching style is marked by an alert, almost predatory smile that Charlie Decker compares to the shark in Jaws—a smile that makes his stomach hurt and his breakfast start to move around. She is quick to mock students who struggle, as when she offers to lend Billy Sawyer a thesaurus after he fumbles an explanation, and she dismisses Carol Granger's attempt to elaborate on an equation with a curt "I don't know what he means." Her classroom is decorated with notices from the Mathematical Society of America, Peanuts comic strips, and a poster of Bertrand Russell bearing the quote "Gravity alone proves the existence of God." She keeps her algebra book and a stack of others neatly on the corner of her desk, and her green attendance book is used by Charlie to call roll after the shooting.
The Murder and Its Immediate Aftermath
On the morning of the crisis, Charlie Decker is called to the principal's office. After a confrontational meeting with Principal Thomas Denver, he returns to his locker, sets its contents on fire, retrieves a pistol from his jacket, and walks to Room 16. When he enters, Mrs. Underwood is at the blackboard, writing an equation and lecturing: "So you understand that when we increase the number of variables, the axioms themselves never change." She looks up alertly, pushes her harlequin glasses up on her nose, and asks, "Do you have an office pass, Mr. Decker?" Charlie replies, "Yes," takes the pistol from his belt, and shoots her in the head. She falls sideways onto her desk and then rolls onto the floor, the expectant expression never leaving her face. Charlie later reflects that she never knew what hit her. The phrase "the axioms themselves never change" becomes a recurring motif in Charlie's narration, a line he returns to as a kind of philosophical anchor amid the chaos. After the shooting, Charlie sits behind her desk, pushing her feet out of the way to get his own into the kneehole, and places the pistol on her green blotter. Her body lies on the floor throughout the hostage standoff; at one point Charlie kicks it with his foot, leaving a footmark on her sweater, and later notices a fly washing its paws on her forearm. He waves the fly away with a feeling of disgust, thinking she looks no more important than a woodchuck he once shot.
The Students' Reaction and Thematic Significance
The students' response to Mrs. Underwood's death is strikingly muted. When Irma Bates breaks the silence with a high, gobbling scream, no one picks it up, and she stops as if ashamed. The class settles into a state of stunned, detached observation, watching Charlie as if he had just announced a pass to the drive-in. Charlie himself notes that American kids labor under a huge life of violence, both real and make-believe, and that "Old Book Bags wasn't much shakes by comparison" to the horror movies and beatings they have seen. Her death is not the subject of prolonged grief or outrage; instead, it becomes the backdrop against which the students' own suppressed conflicts—their resentments, their secrets, their desires—begin to surface. Mrs. Underwood's murder is the first and most decisive act of Charlie's rampage, the point of no return that transforms a troubled student into a killer. Yet her death also serves as a kind of release valve for the class, a shocking event that breaks the normal order and allows the students to confront truths about themselves and each other that would otherwise remain hidden. In the end, she is less a fully realized character than a symbol of the institutional authority that Charlie—and, by extension, the novel—sees as hollow, hypocritical, and ultimately powerless to prevent the violence it helps to create.
