Stella Nickell's small-time world was one of big-time dreams. In 1986, her biggest one came true when her husband died during a seizure, making her the beneficiary of a $175,000-plus insurance payoff--until authorities discovered Bruce Nickell's headache capsules had been laced with cyanide. In an attempt to cover her tracks, Stella did the unconscionable. She saw to it that a stranger would also become a "random casualty" of cyanide-tainted painkillers. but Stella's cunning plan came undone when her daughter Cynthia notified federal agents. And troubling questions lingered like the secret of bitter almonds...

Did Cynthia reveal everything she knew about the crimes? The stunning answers would unfold in a case that sparked a national uproar, dug deep into a troubled family history, and exposed an American mother for the pretty poison she was.
