Prime Video has announced that Neagley, the first spinoff of the hit series Reacher, will premiere September 16. The eight-episode series stars Maria Sten as Frances Neagley, the private investigator and former member of Jack Reacher's elite 110 Special Investigators. This time, Neagley is on her own as she investigates the suspicious death of a friend, uncovering a dangerous conspiracy along the way while relying on the skills she learned working with Reacher. Alan Ritchson will make a guest appearance as Jack Reacher. The premiere comes just weeks after Season 4 of Reacher debuts on August 12, with the Neagley launch lining up with that season's finale.
