Thank you for sharing this information regarding your two books! These will be on my list of future purchases. While we devote much time to the Charlie Chan films of Warner Oland, Sidney Toler...and Roland Winters, along with the 1957 TV crime drama starring J. Carrol Naish, the "other" Charlie Chan movies are noted at our site at http://www.charliechan.info/id179.html. Please take a look when you have a moment! In my personal Chan collection I have a copy of an original script for "The House Without A Key."
