Mrs. Singletary is the cashier at a store called the Piggly Wiggly in Barkley Cove. When Kya starts coming into town to buy grits after Ma leaves, Mrs. Singletary takes an interest in her, asking her why her mother never does the shopping anymore. A sympathetic woman, she also helps Kya count out her change, feeling sorry for her and her lack of parental support. Later, Mrs. Singletary testifies during Kya’s trial, saying that she saw her board a bus before Chase Andrews’s murder and return to town the day after his death. In this way, she substantiates Kya’s alibi.
