It has been done, but it's complicated. Evan will send you my email address so you can tell me in more detail what you want to do, and I will tell you if it's possible, and why not.
Dear Mr. Pinkwater:
I grew up reading and being inspired by your books. Now I am sort of an adult and I make theater. I would very much like to adapt one of your books into a theatrical piece. Is this even remotely possible, in terms of rights/permission/how you feel about it? What steps would I need to take?
Thanks,
Sascha Paladino
