Unforgotten

ITV1, 9pm

Strides are made this week towards solving the case but, as so often with this elegant crime drama, the personal subplots are where the stars earn their fees. Sinéad Keenan and Sanjeev Bhaskar excel as DCI Jesse James and DI Sunny Khan, when their private lives start to disintegrate. In adversity, strong detective duos can be forged.
