A Capital Offense opens when bookstore owner Jack Brandon, after attending a meeting of the city council regarding gambling casinos, stops at his church and then drives his pickup to the Katy Trail, where he meets his death. Initially, the evidence (a suicide note and a mysterious twenty-five-thousand-dollar loan) points to suicide, but his wife, Connie Brandon, a devout Christian, believes that he was killed by the casino people. Other evidence surfaces: Jack died of a drug overdose, and a woman claimed that she and Jack were having an affair.

With the help of a policeman friend of Jack, Tick Garner, and his wife, Tess, Connie perseveres.

Wilt gets the video but first shows it to Luke, who then shows it to Connie. The video shows Jack and Sandra Lumsford kissing; Lumsford is the woman who claimed to be having an affair with Jack, but she has vanished. Furious with Jack...
