D.B. is Holden’s older brother. A former army soldier who fought in World War II, D.B. is an author best known for his short stories, which Holden deeply admires. However, D.B. has recently started writing movies in Hollywood, which displeases Holden, who thinks his brother has sold out and is now practicing something close to prostitution. D.B. is the person who visits Holden most frequently when he’s in the rest home.
