I just finished the book and can't help but wonder what ever happened to the people I met there-in during the 30+ years that have followed since publication.
I turned up absolutely nothing on Peter Ryhiner through Google except tracking elephants he caught and the New Yorker Magazine features from the 50's.
I had slightly better luck looking up his wife Mercia. At least someone named Mercia Ryhiner eventually married the actor Rex Harrison. That certainly seems to fit her as she was portrayed by Peter during their few years together.
Does anyone have any idea what ever happened to him?
