The first series of The Bletchley Circle reminded us that sisterhood is powerful. So it’s no surprise when Jean (Julie Graham) feels compelled to defend the innocence of a former Bletchley Park codebreaker, even when the woman refuses to defend herself.
It’s 1953, ten years after Jean crossed paths with Alice Merren (Hattie Morahan) at Bletchley. Now Alice is facing trial for the murder of John Richards, a fellow scientist with whom she’d had an affair all those years ago. Alice hasn’t denied involvement in his murder, but she hasn’t confessed to it either. That’s enough proof of doubt for Jean, who resolves to demonstrate Alice’s innocence. But Jean can’t do it alone; she needs the other members of the “Bletchley Circle” to help her.
(This trailer's from ITV's UK run of the series in January.)
“Blood on Their Hands” (a two-part episode that concludes next week) packs a lot of plot into a scant 45 minutes, and the show’s creators don’t waste any time reviewing the material from Series 1. So, first, a recommendation: If you don’t have total recall of previous episodes, you’ll want to revisit them; it will help put this story in context.
