Harold Larwood was a professional cricketer for Nottinghamshire County Cricket Club and the England cricket team between 1924 and 1938. A right-arm fast bowler who combined extreme speeds with great accuracy, he was considered by many players and commentators to be the finest and the fastest fast bowler of his generation and one of the fastest bowlers of all time. He was the main exponent of the bowling style known as "bodyline", the use of which during the Marylebone Cricket Club (MCC) tour of Australia in 1932–33 caused a furore that brought about a premature and acrimonious end to his international career.

Bodyline, also known as fast leg theory bowling, was a cricketing tactic devised by the English cricket team for their 1932–33 Ashes tour of Australia. It was designed to combat the extraordinary batting skill of Australia's leading batsman, Don Bradman. A bodyline delivery was one in which the cricket ball was bowled at pace, aimed at the body of the batsman in the expectation that when he defended himself with his bat, a resulting deflection could be caught by one of several fielders deliberately placed nearby on the leg side.
