Aunt Sarah is the Old Man’s older sister. Although she was traumatized when their mother, Akumu, abandoned them as children, Sarah remained loyal to their mother for the rest of her life. In adulthood, she remains estranged from most of the Old Man’s family. Tradition dictates that, since she’s unmarried, the Old Man would be responsible for caring for her in adulthood, so she contests the Old Man’s will, believing that the rest of his family is trying to keep his money for themselves. In reality, Zeituni explains to Barack, there isn’t much money in the Old Man’s estate in the first place—and the lawyers’ fees to continue litigating will eat up whatever money is left. Barack finds her somewhat disturbing in her single-minded pursuit of her deceased brother’s money.
