> Order Series 2 on DVD on Amazon.

The official synopsis reads: “…the ladies are reunited for their second case in the first two-part story when former Bletchley Park colleague, Alice Merren (Hattie Morahan) is accused of murder. Jean (Julie Graham) methodically sets to work examining the evidence and is intent on helping Alice after a distinguished scientist is discovered shot through the heart in the study of his home with Alice, gun in hand, standing over him.

“The evidence is stacked against her, but Jean’s instincts tell her differently and she goes to visit Alice in Holloway Prison. Alice is quietly resigned to the fact she will hang.  But why has she offered no defence and why does she refuse to talk? Jean calls on the ladies to reunite, but will they share her faith in Alice’s innocence?

“Susan (Anna Maxwell Martin) is still shaken by the trauma of last year’s events and fears for the safety of her young family. Millie (Rachael Stirling) has secured a highly regarded position translating for German businessman – the old enemy.

“Now working for Scotland Yard as a secretary, Lucy’s (Sophie Rundle) ability to process and recall data (eidetic memory) is vital if the ladies are to investigate Alice’s case.

“Will the women overcome their fears and risk their burgeoning careers to save Alice’s life as the days to the hanging countdown? And what danger will they face as they uncover not only Alice’s secret, but also a much darker one at the heart of the British Army?

“In the second of the two-part stories Millie’s black market dealings with charming rogue Jasper lands her in jeopardy when she becomes caught up in the murky world of people trafficking, bringing her face to face with hard-bitten Marta, a Maltese businesswoman whose family isn’t to be crossed.

“Abducted by Marta’s henchmen, Millie is shocked by what she discovers.  But with her own life under threat can Millie escape and help the imprisoned young women, whose misery her “innocent” side-business has helped fund. And will the rest of the Circle forgive and help her?”
