Torn from the headlines, here is the case that shocked a nation: the Seattle city bus ride that turned to mayhem and murder at the hands of a gunman. Ann Rule unmasks the forces that drove quiet, clean-cut Silas Cool to shoot the driver, causing the bus to plunge off the Aurora Bridge into an apartment building. The catastrophe left three dead -- including Cool -- and dozens injured. While the scene unfolds as in a terrifying movie, Rule finds very real answers to the haunting question "how could this happen?" -- and expertly constructs the unseen chain of events that resulted in an explosive and shattering tragedy.
