In 1852, Herman Melville published what would much later become his most famous work... Moby Dick, or The Whale. He based this work upon a real life horror story that he'd read about. Twenty years earlier, a whaling ship called The Essex had been attacked and sunk by a giant sperm whale. Alone and literally in the middle of the ocean many thousands of miles from civilisation, the crew had to do some questionable things just to stay alive. This week's episode is all about their epic quest for survival.
