First edition The protagonist, Ben Knowles, is from a London manufacturing family. In 1848 he experiences the disorders in Paris and then resolves to move to the United States, the 'New World,' "craving vulgarity and strangeness" (page 6). In New York he encounters Timothy Skaggs, a journalist, novelist and pioneering photographer, Duff Lucking, a fire-fighter and Mexican–American War veteran, and Duff's sister Polly, an actress and prostitute. The novel charts the characters as they journey west and participate in the California Gold Rush.
