In 1990, Patricia Cornwell sold her first novel, Postmortem, while working at the Office of the Chief Medical Examiner in Richmond, Virginia. An auspicious debut, it went on to win the Edgar, Creasey, Anthony, and Macavity Awards as well as the French Prix du Roman d’Aventure prize—the first book ever to claim all these distinctions in a single year. Growing into an international phenomenon, the Scarpetta series won Cornwell the Sherlock Award for best detective created by an American author, the Gold Dagger Award, the RBA Thriller Award, and the Medal of Chevalier of the Order of Arts and Letters for her contributions to literary and artistic development. Today, Cornwell’s novels and iconic characters are known around the world. Beyond the Scarpetta series, Cornwell has written the definitive nonfiction account of Jack the Ripper’s identity, cookbooks, a children’s book, a biography of Ruth Graham, and two other fictional series based on the characters Win Garano and Andy Brazil. While writing Quantum, Cornwell spent two years researching space, technology, and robotics at Captain Calli Chase’s home base, NASA’s Langley Research Center, and studied cutting-edge law enforcement and security techniques with the Secret Service, the US Air Force, NASA Protective Services, Scotland Yard, and Interpol. Cornwell was born in Miami. She grew up in Montreat, North Carolina, and now lives and works in Boston and Los Angeles.
