Pact viewers were completely in shock tonight when the blackmailer was finally revealed.
Fans of the BBC One drama were left with their mouths open as the person asking for the money wasn’t someone anyone would have guessed.
Tonight, a seemingly clean and squeaky Nancy, played by Julie Hesmondhalgh, was on display as the blackmailer.
The series focuses on a group of four women who accidentally kill their horrible boss after a prank goes awry.
They left him tied to a tree in the woods, but after returning to find him, he was dead.
They all made a pact to keep what they had done secret.
