The Elephant Whisperer
Usually, African game wardens did not talk to or go near the elephants because this can change their natural behavior.  But these elephants were so angry at and afraid of humans that Anthony decided to do something different.  He decided to make friends with them so they would not hate humans.  In the book, he tells the reader how he became friends with the elephants, caught poachers, made deals with African humans who lived nearby, for example the Zulu king and chiefs, took care of a sick baby elephant, and ran the game preserve.
