EastEnders fans are sure they've worked out how Shirley Carter will take Sam Mitchell down.
Shirley was there when two gunmen headed into Peggy's, with Sharon Watts and Kat Slater left in the firing line. However, Sam showed up and it was her who got shot.
But now it's all been revealed that Sam had planned it all - something which Shirley herself has now realised, and she is blackmailing the recent Albert Square returnee after discovering Sam was behind the raid.
