The Four Fists by F. Scott Fitzgerald

Of course, after the third blow Samuel put in several weeks at conscientious introspection. The blow years before at Andover had landed on his personal unpleasantness; the workman of his college days had jarred the snobbishness out of his system, and Marjorie's husband had given a severe jolt to his greedy selfishness. It threw women out of his ken until a year later, when he met his future wife; for the only sort of woman worth while seemed to be the one who could be protected as Marjorie's husband had protected her. Samuel could not imagine his grass-widow, Mrs. De Ferriac, causing any very righteous blows on her own account.

His early thirties found him well on his feet. He was associated with old Peter Carhart, who was in those days a national figure. Carhart's physique was like a rough model for a statue of Hercules, and his record was just as solid -- a pile made for the pure joy of it, without cheap extortion or shady scandal. He had been a great friend of Samuel's father, but he watched the son for six years before taking him into his own office. Heaven knows how many things he controlled at that time -- mines, railroads, banks, whole cities. Samuel was very close to him, knew his likes and dislikes, his prejudices, weaknesses and many strengths.
