Emma Rodriguez and the Maplewood Detectives are back for their biggest mystery yet! When three eager fourth-graders discover a mysterious map showing secret tunnels beneath their school, Emma, Jake, and Zoe must mentor the next generation of young investigators while uncovering the truth about Maplewood Elementary's hidden past.
What starts as an exciting exploration of forgotten underground classrooms becomes a shocking revelation: their entire school was designed as a secret training facility for young detectives, and they've been part of a seventy-year-old program without even knowing it!
Now the Maplewood Detectives must decide: should they continue being guided by hidden forces, or take control of their own detective legacy? In their most challenging case yet, Emma and her friends discover that the greatest mystery isn't what's buried beneath the school—it's creating a future where every student can become an investigator.
