The things Robert is saying soon get to Miss Sidley, and the terrified teacher decides to take drastic measures. She takes out her deceased brother's Luger pistol from a drawer and puts it in her purse. That day at school, she takes twelve of her students to a testing room where sound is well-concealed, and shoots each one dead. Another teacher comes in as Sidley is preparing to shoot a thirteenth student, and Sidley's bad back gives way as the other teacher struggles with her.
