The Chamber (1994) is a legal thriller written by American author John Grisham. It is Grisham's fifth novel. In 1967, in Greenville, Mississippi, the office of Jewish lawyer Marvin Kramer is bombed, injuring Kramer and killing his two young sons. Sam Cayhall, a member of the Ku Klux Klan, is identified, arrested and tried for their murders, committed in retaliation for Kramer's involvement in the Civil Rights Movement. Sam's first two trials, engineered by his Klan-connected lawyer, each end in a mistrial. Twenty years later, the FBI pressures a suspected associate to testify against Sam at a third trial. Sam is convicted and sentenced to death by lethal gas. He is sent to the Mississippi State Penitentiary and placed on death row.
Now without a lawyer, Sam becomes apro bono case for a team of anti-death penalty lawyers from the large - and Jewish - Chicago law firm of Kravitz and Bane. Representing Sam is his own grandson, Adam Hall, who travels to the firm's Memphis office to aid Sam in the final month before his scheduled execution. Although lacking experience in death penalty cases, Adam is determined to argue a stay for his grandfather. Sam, despite his violent past, is one of the few living links to Adam's family history. Sam's alcoholic daughter, Lee Cayhall Booth, slowly reveals the family's tragic past to her nephew, Adam.
Initially uncooperative, Sam eventually opens up to Adam and reveals a remarkable depth of hard-won legal knowledge, regularly preparing his own briefs and court motions. Adam interviews the FBI agent in charge of the original case and realizes that Sam almost certainly did not commit the actual crime for which he had been found guilty, although he was present. Nevertheless, Sam has a long and largely-secret history of Klan-related crimes, including several murders. Dogan, the associate who testified against Sam at his third trial, has apparently been murdered by the Klan. Sam himself will not reveal if another associate exists, thus not violating the Klan's loyalty oath.
