The Bulwark

Hannah and Rufus Barnes, both Quakers, move out of Maine to Trenton, New Jersey, where Hannah's widowed sister lives. Their son Solon, the protagonist, meets Benecia Wallin; although she is affluent and he is not, they get married. Solon works in a bank in Philadelphia, where his Quaker values are contrary to financial ethos. He summons a bank examiner from Washington DC to stop the corrupt practices of some chief executives. Eventually, he resigns. Meanwhile, two of his offspring, Etta and Stewart, repudiate their Quaker upbringing. While Orville gets married and Isobel works in a college, Etta moves to Wisconsin and then Greenwich Village under the influence of one of her friends, Volida La Porte. She has an affair with a painter, until he decides to go West to further his career. Moreover, Stewart accidentally kills one of his dates and commits suicide shortly after. Eventually, Benecia dies upon Etta's return; Solon dies of cancer as Etta watches over him.
