Coronation Street fans are concerned that Tracy Barlow may kill again, and Cathy Matthews could be the unlucky victim.
During Tuesday's episode of the ITV soap, Cathy (Melanie Hill) was left shaken up when she was sent a floral funeral wreath on her birthday.
Viewers were convinced that it was Tracy who sent the threat to Cathy, as she owns a florist, and was also seen verbally abuse Cathy earlier in the day.
Taking to Twitter, one person wrote: "Wonder if florest Tracy knows anything about the wreath... #corrie (sic)."
Another viewer posted: "#corrie Tracy Barlow you are becoming the image of your mum Deirdre and Grandma Maude .Did you send that reef (sic)."
A third person tweeted: "Tracy's proper Toxic #Corrie," while a fourth added: "Tracy is the biggest hypocrite going. She's bullied more people than I've had hot dinners. @itvcorrie #Corrie."
Another Corrie fan feared that Tracy will go one step further and harm Cathy, and possibly even kill her.
"When Tracy says "I'm gonna flammin kill her". We know she is one person who is more than capable. #Corrie #CoronationStreet (sic)," one concerned viewer tweeted.
Cathy decided to confront Tracy about the wreath, but Tracy laughed in her face before shouting at her and calling her a "daft old bint".
Last week, the newsagent owner finally admitted that it was her, rather than her partner Brian, who left the nasty comment online after Tracy refused to let her help with Steve's fundraising.
And it seems one person simply cannot let it go, with Tracy constantly referring to Cathy as a "troll".
Tracy is certainly no stranger to harming people and bludgeoned her boyfriend Charlie to death after she found out he was having an affair.
But is Tracy simply managing to keep a straight face and planning something more sinister for Cathy in the near future? Or does she have a stalker lurking nearby?
