When fourteen-year-old Mattie Sullivan asks Spenser to look into her mother's murder, he's not completely convinced by her claim that the police investigation four years ago was botched. Mattie has been left to care for her younger siblings and an alcoholic grandmother in a dilapidated apartment in South Boston. But her need for closure and her determination to make things right hit Spenser where he lives. Mattie believes the man convicted of the crime is innocent, and points Spenser to the Southie toughs she saw carrying her mother away hours before her murder. He will need Hawk's help to find peace for Mattie.--From back cover.
