The Case of the Missing Time Capsule

A missing time capsule. A mystery buried for fifty years. And secrets that hit close to home...

When Oakwood Middle School plans to open a 1974 time capsule as part of its anniversary celebration, The Curious Club is surprised to learn their own grandparents were part of the original project. But excitement turns to suspicion when the time capsule vanishes just days before the big event.

As Hannah, Julia, Rohan, and Jaden dig deeper, they uncover a decades-old cover-up involving environmental crimes, shady politics, and a secret someone is still willing to protect-no matter the cost. The search for the truth leads them through hidden records, anonymous threats, and unsettling family revelations.

This time, the mystery isn't just about what happened-it's about who they are.

The Case of the Missing Time Capsule blends thrilling detective work with big-picture themes like integrity, legacy, and standing up for what's right-even when the truth is complicated.

Perfect for fans of Greystone Secrets, City Spies, and A Good Kind of Trouble, this fourth book in The Curious Club Mysteries series will keep readers hooked from the first clue to the final reveal.
