Published in 1924, when the cracks in the British Empire started to appear, E.M. Forster 's A Passage to India deals with the trial of an Indian doctor accused of raping an Englishwoman. The work was the last of Forster's novels, and a thematic change for him as well. Previous novels such as A Room with a View (1908) (read my post here) and Howards End (1910) stayed in Europe, focusing on the familiar Edwardian theme of the individual's struggle against the oppressive conventions of society. Influenced by Forster's own travels to India in 1912-13 and 1921, A Passage to India has been praised not only for its critique of the British Empire, but also for its stylistic innovation and philosophical intensity. The novel offers a way of thinking critically about our relationship to the world, and our relationship to ourselves.
