The Bletchley Circle
A group of ordinary women continue using their code breaking skills to solve crimes.

Season 2  (Aired April 13 – May 4, 2014)

The Bletchley Circle returned for a second season in 2014. The first episode, Blood on Their Hands opens with former Bletchley Park girl Alice Merren in prison awaiting trial for murder. Jean stands behind her innocence and tries to reunite the circle in an attempt to help one of their own. Lucy is now getting on well in a clerical job at Scotland Yard and keeping her head down, and Millie is working as a German translator. Susan is reluctant to get involved after her experience with the twisted serial killer Malcolm Crowley and the danger it posed to her family. 

Next, in Uncustomed Goods, Millie branches out into what she believes to be a harmless sideline of dealing in uncustomed goods. This endeavor leads her to be kidnapped and held in a seedy hotel by gangsters. On discovering this, Alice goes to Jean and Lucy for help. The girls start investigating in order to save their friend and, as they do so, uncover a much darker, hidden world of crime.

A Closer Look at Season 2

Season 1  (Aired April 21 – May 5, 2013)

With an extraordinary flair for code breaking and razor-sharp intelligence skills, four seemingly ordinary women become the unlikely investigators of a string of grisly murders in this original thriller, set against the backdrop of post-war London.

Season 1 Preview Follow four women with the extraordinary ability to break codes.

It’s 1951 and Susan, played by two-time BAFTA award-winner Anna Maxwell Martin, Millie (Rachael Stirling, Women in Love), Lucy (Royal Academy of Dramatic Art graduate Sophie Rundle) and Jean (Julie Graham, William & Mary, Survivors) have returned to post-war domesticity, modestly setting aside the part they played in the Allied victory. Their brilliant work at top security HQ Bletchley Park helped crack the codes used by the German military, producing crucial intelligence that shortened the war.

Susan’s conventionality masks a sharp, inquisitive mind. She may appear every inch the typical 1950s wife and mother, but when she hears about a string of unsolved murders in London, Susan’s old Bletchley spirit is ignited. With her handwritten charts of numbers, dates and times, and lines of wool connecting the dots on her wall map, Susan has spotted a pattern of behaviour in the killer that no one else sees. Unaware of her background, the police dismiss Susan’s theories causing her to realise that the only way she can solve the murders is with the help of her friends.

Secretly, Susan reconvenes the formidable foursome — bohemian and streetwise Millie; Lucy, with her brilliant photographic memory and Jean, the methodical no-nonsense organiser. A race against the clock ensues as the women work to outwit the culprit. Can they rekindle their singular expertise and discover the killer’s next move — before he strikes again?
