Sarah Parish and Faye Marsay starred as Det Supt Elizabeth Bancroft and DS Katherine Stevens, who clash when Stevens begins investigating a cold murder case from 27 years ago – a case that Bancroft suspiciously wants her to stay away from.
Viewers who were gripped by episode one had their own theories about what twists could be ahead in the plot:
The murdered woman was pregnant with Bancroft's ex husband's baby. #Bancroft
I’ve got a feeling her ‘son’ isn’t actually her son and it’s the dead woman’s and if I’m right and Katherine is the murdered woman’s daughter then they’re brother and sister. That’s my theory #Bancroft
