Adam may have been hoping to extort money from Aidan, but what he hadn't reckoned on was Eva already knowing about her partner's affair with Maria.
Next week's episodes of Coronation Street will see Adam realise that Eva must know more than she's been letting on when he prepares to drop his bombshell, only for her to suggest that they meet in the ginnel.
In this sneak peek scene from Monday's double bill, Adam shows Eva the image of Aidan snogging Maria, which is actually the first time Eva has seen photographic proof of the infidelity.
But then comes the moment when Eva asks Adam to stop blackmailing Aidan as she wants to forget about his affair for the sake of their baby.
Only viewers (and not Adam) know that Eva isn't actually pregnant at all, but will he work out that there's more to her tale than meets the eye? Or is Adam going to reluctantly agree to back down?
Watch the scene from Monday's episode below. Beneath that, there's a 60-second rundown of all next week's drama on Coronation Street
