Hi Joann,
Ok, Since I don't have The Scarlet Clue,I went to the Charlie Chan gallery and found a picture from that movie that, I think, shows the same desk as in your picture. It's the picture with this caption:

"Gloria Bayne attempts to blackmail Ralph Brett, showing
him the matchbook that he left behind in her car.
Lobby Card"

The desk in your picture looks to have the same objects on it and there is a picture on the wall that appears to have the same frame as in your picture.

Final guess, The Scarlet Clue.
Am I right? Do I win a million dollars?

Jack

Yes, Jack! You're right, alrighty!
Very good super sluthing considering you
don't have the movie, you've impressed the heck
out of me!
...OK, OK, So didn't win quite a million, none the less you
definately won my admiration for your accurate
guess. Joann

If you only have but one guess, make sure that guess
is right!

Hi Joann,
Thank you. I enjoyed the challenge.

Jack
