Reacher season 3 will air on Prime Video in 2025, and it'll potentially set up the Frances Neagley spin-off that has just been announced. Maria Sten has played Neagley in both seasons of the hit action series, and will reprise the role in the spin-off in addition to appearing in the upcoming season 3, which is based on Lee Child's book, Persuader. The expansion of the Reacher universe with the Neagley spin-off is exciting for fans, and the upcoming season should set up more spin-offs, to capitalize on the popularity of the franchise.
