Along the Bay of Bengal, between the countries of India and Bangladesh, stretches a strange and beautiful landscape—part ocean, part river, part forest. This is the Sundarbans Tiger Reserve, and it is home to more tigers than anywhere else on the earth. Nowhere else do tigers live in a mangrove swamp. Nowhere else do healthy tigers routinely hunt people. Yet about three hundred people a year are killed by the tigers of the Sundarbans. And no one knows why.
