Trailer: The Bletchley Circle Series Two

The Bletchley Circle Series Two will be screened on ITV1 on Monday 6 January at 9pm.  

The series, based on the lives of four extraordinary and brilliant women who worked at top-secret HQ Bletchley Park during World War Two, features two self-contained stories each played out across 2 x 60 minute episodes written by series creator Guy Burt.

Set a year on from the first series in 1953, 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?
