A young man in a poor quarter on the edge of Tunis knocks his mother unconscious, binds her, burns her alive, and then awaits execution. From his cell he presents the act as his answer to years of neighborhood talk about her and the humiliation it brought him. In alternating chapters the mother tells her own story of a poor, neglected marriage and her refusal to live entirely by the quarter's rules.
The book sets the killer's account beside the victim's and adds no narrator to rule between them. Each voice fills in context the other leaves out, so the reader must hold two partial truths at once instead of accepting either self-justification. The crime becomes a collision of two survival logics, not a simple case of villain and victim.
In the tight-knit poor quarter, talk about a woman's conduct becomes public, and the mockery falls on her son. The novel makes this gossip one strong force behind the killing. It also shows his own resentment, his hallucinations, his deliberate planning, and the pleasure he takes after the murder, so the act is not simply the neighborhood's will carried out through him.
The mother describes a life that poverty and a joyless marriage reduced to endurance, and one affair after she is widowed that she treats as a claim to her own life. She rejects most of the sexual accusations the quarter makes against her as invented. The novel sets her limited pursuit of pleasure against a community whose scandal outruns what she actually did.
