text: I saw this when I was twelve. It was the movie that made me understand what a good mystery really was. I had read the entire Happy Hollisters children's mystery series and they were about a family of child sleuths who always got their man. But we the readers were not in a position to solve the mystery along with them. This movie showed me that a good mystery is that which makes the viewer/reader, at the end, say, "OH!!!!! OF COURSE!!!!!!!"
