Weatherfield seemed peaceful, until Maggie Driscoll appeared – a polite, open-minded woman, but carrying a dark streak from many years ago.

In a special flashback about to be shown, her terrible secret is revealed: Maggie was involved in a murder.

Ben – who Maggie helped finance to buy the Rovers pub – accidentally overheard a conversation that made the audience shiver.

Maggie once said: “When someone dares to hurt my child, I only have one way to deal with it.” And then the scene changed to an image of a bloody hand.

It is not clear who the victim is, but many fans guess it could be related to the Connor family or someone who mysteriously disappeared many years ago. What is even more horrifying is that Maggie’s entire family – son, daughter-in-law, and young grandchildren – do not know anything about that past. When the secret is revealed, everyone will have to ask: “Who have we been living with all this time?”

Coronation Street described this as the “darkest storyline of the year” – a mix of detective, psychological and crime. And Maggie, the seemingly gentle woman, becomes the center of the storm that causes panic in the whole neighborhood.
