Three trustees of the Van Traylen fund have died suspiciously during the last nine months. A bus load of the trust orphan kids are almost killed. Police Colonel Bingham (Christopher Lee) suspects that someone wants the trust money for themselves and he recruits Dr. Ashley (Peter Cushing).
This sets up an interesting mystery. It also has yet another pairing of Lee and Cushing. It could go somewhere with these ingredients. Instead, it gets tied down by one child's story and other characters doing the investigating. It seems to meander in circles for the first act. Most of that section with Peter is unnecessary. He's better off as a random doctor given her case. Lee and Cushing are moving at a snail's pace. They should be Sherlock and Watson but they are too far behind the audience. They come off looking clueless or somewhat uncaring. They take way too long to get to the orphanage. Anna Harb is a more interesting character. At least, she's more active and more invested. Finally, there are the kids. I don't know if the child actors are any good. The movie needs them to do more. They need to get into this movie sooner, front and center. They are the children of the bus. That's a better title.
