What's the full name of the person the young attorney is related to?
In April 1967, the office of Marvin Kramer, a Jewish civil rights lawyer in Indianola, Mississippi, is bombed by the Ku Klux Klan, killing Kramer's five-year-old twin boys and leading to the amputation of Kramer's legs and his later suicide.  Klansman Sam Cayhall is tried for murder in the bombing, and is eventually convicted and sentenced to die in the gas chamber at the Mississippi State Penitentiary.  Twenty-nine years later, in 1996, Adam Hall, a young attorney at the Chicago law firm of Kravitz and Bane, seeks assignment to the firm's pro bono representation of Cayhall in the last weeks before his scheduled execution.  Adam is Sam Cayhall's grandson, his family having since moved away from the South and changed their name, haunted and shamed by Cayhall's crime.  Adam is motivated to take the case in a search for some understanding of the dark secrets of his family, which prompted the suicide of Adam's father the year Sam was sentenced to death (and whose body Adam found as a child).
