Of course, there would be some changes made in any "movieized" version of "Keeper of the Keys." There are twists, turns, and suspects in the story, but it was not an action story. I feel that a small part of the story was used as a part of the basis of "Charlie Chan in Reno," but just a snippet. I still think that it could have been made into a film, but, perhaps the folks at Fox felt similarly to you on the matter!
