"The Swoop! or, How Clarence Saved England: A Tale of the Great Invasion" by P. G. Wodehouse is a short comic novel published in 1909. England faces simultaneous invasion by nine foreign armies, but the British public remains oddly indifferent, more concerned with cricket scores than military threats. When invading commanders become distracted by music hall opportunities, an unlikely hero emerges: fourteen-year-old Clarence Chugwater and his Boy Scouts. This satirical tale lampoons the popular invasion literature of the era. (This is an automatically generated summary.)
