Madalyn Murray O'Hair, the notorious atheist who launched the Supreme Court case taking prayer out of America's public schools, was also the victim (along with her son and granddaughter) in a brutal Texas murder that went unsolved for years. Dracos, a print and TV journalist who has consulted for America's Most Wanted, reviews the case in full true-crime mode, the prose purpler with every page. But in a departure from genre conventions, the book heaps more abuse on the victims than the killer. It's one thing to deflate the "godless Joan of Arc" legend built up around O'Hair by discussing the shortcomings in her legal arguments or speaking candidly about her pervasive bigotry, but those revelations are just a warmup for gratuitously cruel swipes at her physical appearance and lurid intimations of lesbian incest. (There's even a brazen assertion that her husband was paid to marry her by the FBI so they could keep tabs on her.) For all its excesses, though, the narrative handles the family's disappearance and the subsequent investigations well, describing how an ex-convict finagled his way into O'Hair's inner circle and manipulated her and her finances, making it look as if O'Hair had fled the country. The ruse was good enough to fool the local police (portrayed here as bumbling incompetents) for years, until an investigative reporter and a private eye began to uncover the details. The book's pulp sensibility, complete with fevered imaginings of O'Hair's thoughts, may obscure the subtleties of her life, succeeding only in its main priority of unraveling the mystery behind her death.
