Coronation Street will air the moment Fiz Brown's dark secret is exposed to her new partner Phill Whittaker next week on the ITV soap.
The truth about her past, and the fact she's kept this from him, comes to light when she comes face-to-face with a blast from the past.
Prior to this, Phill and Fiz's romance has been going from strength to strength, despite her clear reservations about their new life together.
They've moved into a new big house together away from the street, with her daughters, and Fiz seems happy with Phill.
But next week this could all change, when she agrees to to meet up with Phill's friends Graham and Angela for a double date.
As the quartet meet though, Fiz is faced with someone from her past and her secrets are exposed.
It emerges Phill has no idea that Fiz was once married to a serial killer, John Stape, and that she too faced trial over fraud charges as well as murder.
Of course the crimes were actually committed by John, and eventually Fiz was freed from prison after an appeal.
More than 10 years on and Fiz has put it all behind her, but she clearly hasn't told Phill about John, her past or the fact her daughter Hope is John's child.
Next week, his friend Graham recognises Fiz at their double date, and he soon confesses they have met before.
Fiz is shocked and worried about the truth coming out, as Graham explains that he was the solicitor for the prosecution.
Fiz confides in Tyrone how she’s never told Phill about John and what happened with him and beyond, but she fears it's only a matter of time before he does learn the truth.
So when Phill does realise what has gone on, what will he think about it all and how will he react?
Later in the week, Michael is fascinated to realise Fiz was married to John the serial killer, but out of humiliation she storms out.

Coronation Street airs Mondays, Wednesdays and Fridays at 8pm on ITV and ITV Hub.
