Carter fans, get ready to sharpen your pitchforks - it looks like there may be trouble ahead for Carla Connor and Peter Barlow.

The last few months have been relatively smooth sailing for the fiery couple on Coronation Street, but a storm is brewing in the form of Abi Franklin.

Next week on the ITV soap, Abi secretly relapses and waits until boyfriend Kevin has left for work before taking a fix.

However, Abi is interrupted by Peter and she stuffs the drugs down the side of the sofa.

She insists to Peter that she didn't take anything from the hospital and he seems satisfied when he leaves.

But Abi is furious when she discovers that the morphine has gone and later confronts him in the Rovers backyard.

How will Peter react?

Later on in the week, Peter tries to tell Abi she needs to get help when he calls round at Number 11.

Meanwhile, Carla is suspicious when Peter lies about where he is going and discovers that he is actually helping Abi with her addiction.

Carla warns him to be careful as Abi used to be in love with him not so long ago.

Elsewhere, Kevin sister Debbie arrives at the house with her suitcase and warns Abi not to mess her brother about.

Abi insists that she wouldn't dream of it but Debbie isn't convinced.

On Friday, Abi assures Peter that she will attend the meeting later but quickly shuts off the call when Kevin and Debbie walk in.

Abi is forced to accept Debbie's offer of lunch, but disappears as soon as she has eaten.

Debbie is incredibly suspicious - will she discover what has been going on?
