ENDEAVOUR – SERIES Season 3 (NR) PBS Masterpiece Mystery! DC Endeavour Morse (Shaun Evans) and DI Fred Thursday (Roger Allam) return in a quartet of new Masterpiece Murder mysteries, each unique and breathtaking in their complexity. Last seen languishing in a prison cell and framed for a crime he didn’t commit, Endeavour is compelled to return to duty when a young woman’s baffling murder requires his singularly cerebral mind to solve. As both men struggle to find their bearings amidst the rapidly changing climate of early 1967, these four new cases set against the dreaming spires of Oxford test their partnership in unexpected ways, as Colin Dexter’s iconic detective is pushed to new extremes in his unrivaled commitment to truth and justice.
