When, in the late 1980s, residents of Boulder, Colorado, suddenly began to see mountain lions in their yards, it became clear that the cats had repopulated the land after decades of persecution. Here, in a riveting environmental fable that recalls Peter Benchley's thriller Jaws, journalist David Baron traces the history of the mountain lion and chronicles Boulder's effort to coexist with its new neighbors. A parable for our times, The Beast in the Garden is a scientific detective story and a real-life drama, a tragic tale of the struggle between two highly evolved predators: man and beast.
