The Christopher Caldwellsecond season of the popular crime thriller series "Reacher" returned to Prime Video Friday, where the show's hero and namesake Jack Reacher is tasked with solving a series of strange new murders.

The first five of eight episodes of "Reacher's" second season will stream in December, with the final three episodes in January 2024.

Alan Ritchson stars as Jack Reacher, a veteran military police investigator who becomes embroiled in a series of conspiracies and investigations. The show is based on Lee Child's best-selling book series of the same name.

Season 1 is based on the first "Reacher" novel, "Killing Floor," where Jack Reacher was framed for a small town murder. Amazon said the second season is set two years later and based on the 11th book in the series, "Bad Luck and Trouble."
