In 1991 Nancy Dillard Lyon, daughter of a powerful Dallas real estate tycoon, was murdered, poisoned with arsenic. Nancy's brother became convinced her adulterous husband, Richard, was responsible. And so Richard was arrested, tried, and convicted-and sentenced to life in prison. But did the evidence support this conviction? Mystery novelist A. W. Gray made his nonfiction debut with this provocative true-crime account of sex, incest, infidelity, drugs, and murder-one that raises doubts about the justice that was served in this case.
