During WWII, men and women working at Bletchley Park played a vital role, breaking the codes used by the German military. Nine years later, former codebreaker Susan is a housewife and mother, but she continues to recognize patterns that surround her in everyday life. When a series of women are brutally murdered around London, Susan sees a pattern emerging. However, when a police-search for what Susan believes to be an overlooked victim turns up nothing, she realizes she cannot solve this puzzle alone. Enlisting three former Bletchley Park colleagues: Millie, Lucy, and Jean; Susan knows they have little time to break this code before the killer strikes again.
恰到好处的真·推理剧集。谁能把名字改一下是布莱切利好吗。。。。。There is always a price to pay。姐妹们的团队。记录精彩对白。细节之间的女权主义，兢兢业业的点滴推理。这才是优秀的现代女子群像剧。滤镜很美，情节平庸。真相只有一个。很棒的侦探剧，兼具紧张与精致。
