When a mysterious package leads attorney Mia Hale and artist Jake Reyes to a university radio archive, they uncover hidden financial data embedded in decades-old broadcasts. The discovery points to a long-buried money-laundering network disguised as a respected arts foundation—and to the suspicious death of the archivist who first heard the signal beneath the music. As Mia and Jake race to decode the remaining recordings, they must expose a conspiracy that has endured for generations before its guardians silence them as well. The Last Frequency is a thoughtful, atmospheric thriller about memory, justice, and the truths that wait to be heard.
