by Lewis E. (Lewis Edwin) Theiss
A teenage Henry Harper spends his days in his father’s backyard workshop, where the Camp Brady Wireless Club meets to tinker with radios and practice secret codes. When a shocking newspaper headline reveals that German forces have somehow learned about a U.S. transport fleet, Henry’s imagination races to a hidden “secret wireless” that might be feeding the enemy. Determined to protect his country, he convinces the club that they can help uncover the mysterious station that’s leaking information.
Henry writes an eager letter to his idol, Captain Hardy, hoping the young officer will green‑light a new mission for the boys. The reply arrives quickly, but instead of the enthusiastic approval Henry expected, it points to a larger problem—underfunded secret services and political roadblocks. Undeterred, Henry and his friends are left to decide whether they can take matters into their own hands, setting the stage for a daring youth‑driven spy hunt.
