Tracy Barlow will become the main suspect for the murder of Tina McIntyre in Coronation Street.
The soap superbitch - who is played by Kate Ford - will be left furious after she discovers the brunette stunner (Michelle Keegan) has been getting close to her boyfriend Rob Donovan (Marc Baylis) and will be in the firing line when Tina is found dead next year.
A show insider told the Daily Star newspaper: "Tracy's got form for murder so she has to be the prime suspect when Tina turns up dead.
"Tina is not exactly a pushover but is she really a match for Tracy? History suggests not."
Tracy - who got out of prison on a technicality after murdering Charlie - is so disgusted by Rob's behaviour she leaves him to run their pawn shop on his own.
The brunette beauty's mother Deirdre Barlow (Anne Kirkbride) asks her: "You not going to work today?
"You've given up on the shop as well as on Rob."
But Tracy hits back: "No I haven't. That shop is half mine. He can just run it by himself for a while - see how he likes it.
"Rob's to blame for all of this, and her, Tina, the neighbourhood tart.
"He's only sorry he got caught out."
