Will Trent Season 4: Marion Must Return Before Sara Linton Arrives

When Will Trent returns for season 4, it must hold off on introducing Will's endgame from the books and bring back his ex instead. The ABC cop show is based on Karin Slaughter's book series of the same name. Although much has changed in the onscreen adaptation compared to the novels, Will Trent still features all the important characters from the text.
