In 2015, an American hunter named Walter Palmer shot and killed a lion named Cecil. The lion was one of dozens slain each year in Zimbabwe, which legally licenses the hunting of big cats. But Cecil's death sparked unprecedented global outrage, igniting thousands of media reports about the peculiar circumstances surrounding this hunt. At the centre of the controversy was Dr. Andrew Loveridge, the zoologist who had studied Cecil for eight years. In Lion Hearted, Loveridge pieces together, for the first time, the fascinating life and murky details of this beloved lion's slaying.
