This is a pretty good mystery based on a novel by Earl Stanley Gardner. The hero is not Perry Mason. It was made in the early seventies as a made for TV movie starring a young Jim Hutton in a pre Ellery Queen role.The movie looks like a pilot for a TV series. Jim Hutton went on to make the Ellery Queen Mystery series for TV.The video quality of the DVD is not good. It looks like it was made from an old VHS video tape. So I wouldn't advise paying too much for it, But if you can get it cheap it's worth it.This is a nice little movie to watch on a Saturday night.
