John Grisham The chamber

The Chamber (1994) is a legal thriller written by American author John Grisham. It is Grisham's fifth novel.
The story begins with a recounting of Ku Klux Klan member Sam Cayhall’s involvement in a fatal bombing in 1967. The target was a young Jewish lawyer by the name of Marvin Kramer. Sam’s partner-in-crime was a man by the name of Jeremiah Dogan. Dogan was the Imperial wizard of the Mississippi branch of the Klan at the time. The third person involved with the bombing was a man who went by the name of Rollie Wedge. Wedge was the true explosives expert, Sam and Dogan were just hateful people who wanted to put a scare into the Jewish Marvin Kramer. This would be their sixth bombing as a group, and like the others, the plan was to set a bomb with a 15-minute fuse inside the building in the middle of the night, and drive away without anybody suspecting a thing. However, Rollie Wedge had different plans. After they had planted the bomb and ran away to a truck stop to go their separate ways, Sam felt that it was rather odd that he hadn’t heard or felt the explosion like he had in the five previous bombings. Curious, he drove back into town to see if everything had gone according to plan. He was amazed to find the Kramer building still standing without even a scratch. Sam found the nearest payphone and called Wedge. Apparently, Wedge wanted there to be a little bit more excitement than just a little scare to the locals. He told Sam that he had set a timer on the bomb to go off around 7:45 AM, assuring that Kramer would be in his office when the bomb detonated. Little did he know, however, that at the same time, Marvin Kramer’s five year old twins would be playing in his office before being taken to nursery school. When the bomb went off, the Kramer twins were about fifteen feet away from the centre of the explosion, and they were obliterated. Sam was arrested because he was found driving the suspect vehicle away from the blast.
