Nikki was just a little shocked when she first heard what Justin said, but she soon figured it all out.
Indeed, as Justin said, Karen had a voice recording of her, which was evidence against her. It was just like a ticking time bomb that could explode at any time.
Even if they successfully get rid of William, what would Nikki do if Karen used this matter to blackmail her to do something else?
So no matter what, they had to get the evidence back from Karen. And if they couldn't, they would have to kill her.
"Okay, Dad!" A trace of ruthlessness flashed in Nikki's eyes.
In fact, ever since Karen sent her the voice recording to threaten her, she had been incredibly furious and annoyed with Karen. Even if they killed her in the future, Nikki wouldn't feel any guilt at all.
