Kelly Carvel is an agent for the Committee Of Ten.
He had been a police captain in Los Angeles prior to the start of this series. He was very good and very respected. Then on a murder case, the judge threw out a conviction on appeal due to what Carvel considered an insane technicality and Carvel hit the roof. Angered by the system which treated the guilty better than the victims, he resigned. This left him in short order broke and very bitter. He knew he needed a job but bit the head off anyone who talked to him about one, not especially good during potential interviews.
It was then that he was approached by the Congressman, a particularly influential political leader, well-off and with even wealthier friends. The politician was one of a group that called itself the Committee of Ten. It was made up of people who were tired of seeing the system beaten when it shouldn't have been. Especially onerous to them were the culprits used money and influence to flaunt justice. The Committee felt that since they, too, had considerable money and great influence, they could make a difference. Quietly but, to them, justly.
They needed someone who could be their physical arm. Carvel was their candidate. He accepted.
The teaming made sense. The Committee needed someone to fight for them and Carvel was more than ready to fight. It takes a while for Carvel to get used to working outside the system but his frustration and his anger quickly takes him where he needs to go. Once he was underway, it became apparent that knowing how the system really works can help a great deal when you plan to work around it, not through it.
