Coronation Street first look as Lisa demands answers from 'corrupt' Costello

Lisa Swain demands answers from DI Costello on Coronation Street next week, a new preview has revealed.

The character was left shaken in recent scenes as her 'dead' wife Becky Swain showed up out of the blue. Four years after her apparent death in the line of duty, she was confirmed to be alive and well, hiding out in Spain.

We learned all about what led to her fake demise and how she got away with pretending to be dead for so long. With that it was clear DI Costello knew more than he had claimed, having lied to Lisa for the past four years.

Next week sees the moment that Costello is confronted by a devastated Lisa, and she wants answers. Costello is avoiding her but Lisa's having none of it.

As Costello hides away in his office, Lisa barges in with a defiant look on her face - leaving Costello rattled. She makes it clear she isn't going to be ignored, and immediately questions Costello about Becky's fake death.

In the clip Lisa tells him: "You're avoiding me. I thought we were going to talk." A nervous Costello replies: "We will, just not here." Lisa responds: "Well tough, because I want answers."

Costello exclaims: "And you will get them but now is not the time." With that Lisa locks the door, leaving Costello concerned. Lisa tells him she's "making sure they are not disturbed".

She then says: "Do you know what it's like telling your child their mum is never coming back, to now find out she's been alive the whole time? Is this some sort of sick game to you?"

Costello denied this but stayed quiet, prompting Lisa to tell him: "I wanna know every single detail of what you and her did behind my back. And if you miss anything out or I think you're lying, I'm gonna blow the whistle. I'm gonna go to the press."

He looked very alarmed at this threat, as Lisa vowed to spill the beans if he didn't start talking. So what will he tell her, and what does he know?

It comes after Friday's episode saw Lisa stunned over Becky's true fate. Shaken, she asked what had happened, and why Becky had faked her death.
