Go Geoffrey!
Writer of Cairo Jim and Jocelyn Osgood. Love those books. Actually, funny you said that, I reading the latest one, "Cairo Jim at the Crossroads of Orpheus." It's good so far. The next one comes out this month apparently, but I'll probably get it for Christmas along with the two Young Indy Volumes of DVDs. Sadly, people outside of Australia, have never heard of Geoffrey or Cairo Jim. If I ever become a top filmmaker, man I will do the Cairo Jim movie. I guarantee it.
Max Allan Collins wrote "The Mummy" adaption and did a great job and have ever since tried to get a copy (I borrowed it from a school library).
