Q.E.D.(1982)

Q.E.D. is a 1982 adventure series set in Edwardian England, starring Sam Waterston as Professor Quentin Everett Deverill, a scientific detective who solves mysteries through logic and invention. Drawing inspiration from Sherlock Holmes, the show blends Victorian-era detective work with early steampunk aesthetics, featuring gadgets and scientific ingenuity as tools of investigation. The title references the Latin phrase "quod erat demonstrandum"—the proof is complete. Despite its clever premise and period charm, Q.E.D. struggled to find an audience and was cancelled after a brief run on CBS in the United States and Channel 4 in the United Kingdom. The series remains a cult curiosity for fans of historical adventure and proto-steampunk television.
