The chamber - John Grisham

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.
