BBC1, 9pm, Tuesday

Ruth Wilson’s fact-inspired drama continues to tighten its grip.

In the latest offering, Alison is on the tail of the elusive Dorothy – finding photographs of her from Alec’s stint in India. After speaking to Alec’s handler Coleman and hearing that their “relationship” was likely a cover story, Alison traces Dorothy to Yorkshire and demands to hear the truth. Back in the 1940s, Alison struggles with the aftermath of Alec’s decisions, forced to raise her family in wartime London.
