Marcia Mitchell served as Secretary of Labor for the State of South Dakota, a senior manager for the Corporation for Public Broadcasting, and Associate Director of The American Film Institute; she also has written and published nonfiction in various genres throughout her career. With her late husband, Thomas, she was inspired to investigate and write nonfiction in the counterespionage genre when he, a retired FBI agent, first told Marcia his account of working on the Judith Coplon case in the 1940s and 50s. They also collaborated on the 2008 volume "The Spy Who Tried to Stop a War: Katharine Gun and the Secret Plot to Sanction the Iraq Invasion"--which inspired the 2019 feature-length film "Official Secrets," starring Keira Knightley. After Tom's death in 2010, Marcia continued her research and writing; their collaborative spy projects inspired a fictional series-featuring Maggie Sachet, a quirky FBI agent whose globe-trotting adventures to solve murders were vetted by real FBI agents for accuracy. Marcia is also the author of another upcoming novel, "The Bridge to Somewhere," along with several previously published works of nonfiction, including "Cosmetics from the Kitchen," "Management Strategies for Women," and "Raindance to Research.".
