Football, in the 1880s, was a rough and dangerous game. To address the abhorrent state of the sport, William McCrum, an amateur Irish goalkeeper and the author's great-grandfather, proposed the penalty kick, a new and drastic sanction introduced to the game in 1891. For over a hundred years, this extraordinary phenomenon has not only regulated the conduct of football (also known as soccer) but has also inspired game theories and infiltrated classics of contemporary literature. An enthralling portrait of a lost age, is a family history, a social history, and a history of the world's most popular sport. It considers an extraordinary phenomenon as it examines the penalty kick’s psychological—even philosophical—grip on our imaginations, with its distillation of risk and chance into the penalty shoot-out, an all-or-nothing moment.
