Theo is the protagonist of the novel and is a round and dynamic character whose identity as a “kid lawyer” drives the narrative. At 13 years old, Theo possesses a sophisticated understanding of the legal world that exceeds his years, a result of being the only child of two lawyers and spending his afternoons at their firm. His defining trait is his proactive nature; he doesn’t wait for adults to solve problems, especially when his best friend, April Finnemore, is in danger. Frustrated by what he perceives as the inaction of the professional authorities, he tells his father, “We should’ve been out there on the streets helping with the manhunt” (27). This conviction leads him to organize a search party, distribute flyers, and conduct his own investigation, embodying the theme of The Agency of Youth in the Pursuit of Justice. Theo’s initiative places him in direct contrast with the formal police investigation, suggesting that passion and personal loyalty are often more effective than detached procedure.

Theo’s legally oriented mind is his greatest asset. He approaches the world with a lawyerly perception, frequently questioning claims that lack evidence. This critical thinking allows him to navigate complex situations with adults.
