Equal parts true crime, twentieth-century history, and science thriller, The Poisoner's Handbook is "a vicious, page-turning story that reads more like Raymond Chandler than Madame Curie." —The New York Observer “The Poisoner’s Handbook breathes deadly life into the Roaring Twenties.” —Financial Times “Reads like science fiction, complete with suspense, mystery and foolhardy guys in lab coats tipping test tubes of mysterious chemicals into their own mouths.” —NPR: What We're Reading A fascinating Jazz Age tale of chemistry and detection, poison and murder, The Poisoner's Handbook is a page-turning account of a forgotten era. In early twentieth-century New York, poisons offered an easy path to the perfect crime. Science had no place in the Tammany Hall-controlled coroner's office, and corruption ran rampant. However, with the appointment of chief medical examiner Charles Norris in 1918, the poison game changed forever. Together with toxicologist Alexander Gettler, the duo set the justice system on fire with their trailblazing scientific detective work, triumphing over seemingly unbeatable odds to become the pioneers of forensic chemistry and the gatekeepers of justice. In 2014, PBS's AMERICAN EXPERIENCE released a film based on The Poisoner's Handbook.

At just forty-one years old, Dr. Autumn Klein, a neurologist specializing in seizure disorders in pregnant women, had already been named chief of women's neurology at Pittsburgh's largest health system. More than just successful in her field, Dr. Klein was beloved - by her patients, colleagues, family, and friends. She collapsed suddenly on April 17, 2013, writhing in agony on her kitchen floor, and died three days later. The police said her husband, Dr. Robert Ferrante, twenty-three years Klein's senior, killed her through cyanide poisoning. Though Ferrante left a clear trail of circumstantial evidence, Klein's death from cyanide might have been overlooked if not for the investigators who were able to use Ferrante's computer, statements from the staff at his lab, and his own seemingly odd actions at the hospital during his wife's treatment to piece together what appeared to be a long-term plan to end his wife's life. In Death by Cyanide, Paula Reed Ward, reporter for the Pittsburgh Post-Gazette, describes the murder investigation and the trial in this sensational case, taking us from the poisoning and the medical staff's heroic measures to save Klein's life to the investigation of Ferrante and the emotion and drama inside the courtroom.

Excerpt from The Cyanide Handbook The discussion of the chemical properties, reactions, methods of manufacture, and analysis of cyanide itself, which have been scarcely touched upon in other similar books, will here be dealt with in sufficient detail. An outline will be given of the latest and most approved practice in modern cyanide plants, but without going into minute details of working, which are liable to constant change.
