Yesterday we had a Blackhawk story set in the Amazon. Here's another Amazon story along with some advice. You may thank me someday. When in the jungle looking for someone if you come across a man with a pet ape, and the man introduces himself as Dr. Death, do not tarry, do not linger. Turn around and walk, no, run away from him.
The dumb people in "The Shrunken Heads of Dr. Death" would have benefited from that advice.
