Jacques 'Paris Jack' LeRoy is the mechanic and musician of the New Orleans Resistance cell led by Horton Boone. His talent of music helps others in tough times, taking the "edge off" during their war against The Nazis.
- Horton Boone introduces Jack to B.J. as an anarchist, and a "true believer" in the political philosophy, indicating that Boone had adopted a "multi-tendency" organizing philosophy, wherein leftist activists collaborate for common goals, despite having political or philosophical disagreements.
- Jack's penchant as a Jazz musician, as well as his association with Paris, are possibly inspired by real-world musician Thelonious Monk, who spent significant portions of his career active in the Paris Jazz scene.
