Joseph Millson will appear in the new series of Endeavour, in the guest role of Robert Fenner! His episode airs on Sunday 12th September at 8pm!

New series. It's the start of 1971 - though wearied from the events of the past year, there's no chance of 'light duties' at the CID. Crestfallen and rarely without a scotch in hand, Endeavour finds himself right back in the thick of it when an explosive murder at an Oxford college has potentially far-reaching political ramifications. Meanwhile, the IRA have made a threat against the life of the Oxford Wanderers' star striker, and Endeavour is tasked with the duty of acting bodyguard.

The Radio Times has all the information about the new series.
