In the novel, Scout lives in fear of a ‘malevolent phantom’, a psychologically disturbed neighbour called Boo Radley, who ultimately saves her life. While it is clear that the character is in part based on a reclusive neighbour, in reality, it was Harper’s mother Frances who was the source of much terror and unhappiness.Suffering from depression and violent mood swings, friends in the close-knit Alabama town say that Frances allegedly twice tried to drown her daughter in the bath. As a result, perhaps, the young Harper was regarded as a difficult and aggressive child who would think nothing of punching other children who annoyed her.
