Lou, sorry, no, i'm not the author. And I can't be lifter of veils here.
I found the book a year ago and posted about it http://charliechan.mhoefler.de/charlie-chan-cheeseburgers-root-beer-floats-and-murder/
Back then Jim Rathbone had a facebook page (I added the link to the post). He was talking about a sequel.
I am not very familiar with facebook (registered in january) but as far as I can say, his facebook page has vanished.
So sorry. One should investigate and peek into mystery of the vanishing author ;-)
Sorry. I guess I was a bit hasty. Did a little search.
I recognized the author from his photo. Was easier than I would have thought.
Here he is: https://www.facebook.com/AuthorRathbone
But his last posting is from june 22.
regards M.
