At great personal peril, and at the risk of being the lone ranger in the U.S. today that has put aside last night’s 4th season premiere of Downton Abbey on PBS for the moment, I bring you word of the second series of the brilliant Bletchley Circle, which premieres tonight at 9pm on ITV1 in the UK.

Rest assured, U.S. fans, the series will return to the PBS schedule in April 2014. How about this for a Sunday night line-up on PBS in April? At 8pET, the 3rd series of Call the Midwife continues from its March 30 premiere, followed at 9pET by the second series of Mr. Selfridge which also returns on March 30 and, to cap off the night, the second series of Bletchley Circle which is set to premiere on April 13! Now THAT’s appointment telly.
 

Series 1, which aired in 2012, was set in 1952 and tells the story of four women who used to work as codebreakers at Bletchley Park. A series of murders take place that seem to have a pattern. The police apparently overlook the pattern, so the women start investigating themselves.

Series 2, which premieres tonight on ITV1 in the UK, is set a year later in 1953 and sees Jean (Julie Graham), Susan (Anna Maxwell Martin), Millie (Rachael Stirling) and Lucy (Sophie Rundle) ‘getting the band back together’ when former Bletchley Park colleague Alice Merren, played by Outnumbered‘s Hattie Morahan, is accused of murder.
 

 
Series 2 will be comprised of 4 new episodes, made up of two, 2-part stories. If you haven’t seen, check it out. Well worth the time….
