On a Monday evening in December of 1980, Mark David Chapman murdered John Lennon outside his apartment building in New York City. The Consequence of Gesture brings the reader along a three-day countdown to mayhem. This book inserts Chapman into the weekend plans of a group of friends sympathetic with his obsession to shatter a cultural icon and determined to perform their own iconoclastic gestures. John Lennon's life is not the only one that hangs in the balance. No one will emerge the same.
