For me this tv show is one of the best tv shows released in year 2018. The Bletchley Circle: San Francisco - Season 1 is a 10/10 tv show for me. Before you read this review and before I spoil you the story, watch the tv show, I highly recommend it. You just have to watch The Bletchley Circle: San Francisco - Season 1. The soundtrack is the greatest asset of this tv show. You can watch it online here on and add your own subtitles if you are not native english speaker.
