拉格泰姆時代

The novel centers on a wealthy family living in New Rochelle, New York, referred to as Father, Mother, Mother's Younger Brother, Grandfather, and 'the little boy', Father and Mother's young son. The family business is the manufacture of flags and fireworks, an easy source of wealth due to the national enthusiasm for patriotic displays. Father joins Robert Peary's expedition to the North Pole, and his return sees a change in his relationship with his wife, who has experienced independence in his absence. Mother's Younger Brother is a genius at explosives and fireworks but is an insecure, unhappy character who chases after love and excitement. He becomes obsessed with the notorious socialite Evelyn Nesbit, stalking her and embarking on a brief, unsatisfactory affair with her.

Into this insecure setup comes an abandoned black child, then his severely depressed mother, Sarah. Coalhouse Walker Jr., the child's father, visits regularly to win Sarah's affections. A professional musician, well-dressed and well-spoken, he gains the family's respect and overcomes their prejudice initially by playing ragtime music on their piano. Things go well until he is humiliated by a racist fire crew, led by Will Conklin, who vandalize Coalhouse's Model T Ford. He begins a pursuit of redress by legal action but discovers he cannot hope to win because of the inherent prejudice of the system. Sarah is killed in an attempt to aid him, and Coalhouse uses the money he was saving for their wedding to pay for an extravagant funeral.

Having exhausted legal resources, Coalhouse begins killing firemen and bombing firehouses to force the city to meet his demands: that his Model T be restored to its original condition and Conklin be turned over to him for justice. Mother unofficially adopts Sarah and Coalhouse's neglected child over Father's objections, putting strain on their marriage. With a group of angry young men, all of whom refer to themselves as "Coalhouse Walker", Coalhouse continues his vigilante campaign and is joined by Younger Brother, who brings his knowledge of explosives. Coalhouse and his gang storm the Morgan Library, taking the priceless collection hostage and wiring the building with dynamite. Father is drawn into the escalating conflict as a mediator, as is Booker T. Washington. Coalhouse agrees to exchange Conklin's life for safe passage for his men, who leave in his restored Model T. Coalhouse is shot as he surrenders to the authorities. Younger Brother escapes to Mexico and dies fighting with Zapata's forces during the Revolution.

Interwoven with this story is a depiction of life in the tenement slums of New York city, focused on an Eastern European Jewish immigrant referred to as Tateh, who struggles to support himself and his daughter after driving her mother off for accepting money for sex with her employer. The girl's beauty attracts the attention of Evelyn Nesbit, who provides financial support. When Tateh learns who Nesbit really is, however, he takes his daughter out of the city.

Tateh is a talented artist and earns a living cutting out novelty paper silhouettes on the street. He tries working in a factory, where he experiences a successful workers' strike, but becomes disillusioned when he sees it change little about the workers' lives, although in the final chapter he still describes himself as a socialist. He starts making and selling moving picture books to a novelty toy company, becoming a pioneer of animation in the motion picture industry. Tateh becomes wealthy and styles himself "the Baron" to move more easily through high society. He meets and falls in love with Mother, who marries him after Father is killed in the sinking of the RMS Lusitania. They adopt each other's children, as well as Coalhouse's son, and move to California.
