I saw this show on TV at the time, and later got some episodes of it on VHS (MPI Home Video) under the Title: "Secrets of the Unknown". This show came out soon after the In Search Of series, though, probably, too soon, as witness its short-lived run and uncanny similarity of the topics covered. A match-up of their episode titles shows heavy overlap. Even their disclaimers are almost identical. Notwithstanding that, the subject matter is naturally fertile ground for documentaries, and this series did an admirable job. The series was set in a surreal, library-like mansion, with various tools (computer databases, view-screens, time portals, and the like) to facilitate exploration of the topic at hand in each episode. It gave the show a nice flair, making it more engaging and enjoyable to watch. Recommended for those interested in this genre, or anyone else, for that matter.
