Justice in the Hall: Secret Codex

Justice is back! But the hallways of Public School 23 are trading in their election posters for ancient artifacts. On a field trip to the Cincinnati Art Museum, Justice Madison is ready for art-not a crime scene.

The museum's most priceless object, the ancient Scarab of Truth, vanishes right before her eyes, triggering alarms and sending the city police into action. The case quickly leads Justice and Detective Ramirez away from the quiet galleries and into the dark, abandoned tunnels of Cincinnati's forgotten subway system.

The thief isn't just stealing-they're playing a game. They leave a trail of silver glitter and meticulously crafted numeric codes that only Justice can decipher. With every code she cracks, Justice gets closer to unmasking the thief, who she realizes is one step ahead, using the historic city as their escape route.

Can Justice decode the messages from the Secret Codex before the thief slips away forever?
