Grace
ITV, 8pm
John Simm stars as DS Grace in this two-part adaptation of the bestselling Roy Grace detective novels by Peter James. Tonight’s feature-length opener sees Grace still plagued by the disappearance of his wife Sandy six years before and his increasingly unorthodox investigation methods coming under scrutiny during a local muder trial. An intriguing case of a stag night prank gone wrong, leaving the groom-to-be missing, could provide the key to his redemption though. Co-starring Richie Campbell. Ammar Kalia

Film choice
Red River, 2.10pm, ITV4
One of the great westerns: an epic, oedipal tale acted out on the Chisholm cattle trail, packed with action and colourful characters. John Wayne’s Dunson is an old westerner clinging to outmoded values; only a confrontation with his adopted son (Montgomery Clift) offers hope of redemption. Paul Howlett
