Fans of Emmerdale are convinced Dr Manpreet Sharma will turn out to be a serial killer.
The village hasn't had a serial killer since Lachlan White was caught for his own killing spree last year.
He killed his mum, grandad, best friend and a conman during his reign of terror in the village.
But now the debt-ridden doctor has shown her evil side and fans are convinced there's more to come.
Earlier this week Manpreet's patient Derek died after she mocked his insistence he was ill and sent him away.
After his death, for which her husband Rishi was being blamed, Manpreet took serious action and stole from Derek's estate.
She took his valuable stamp collection to Eric Pollard to get him to sell it so she could use the money to bribe the Environmental Health inspector into dropping the investigation.
It worked and he agreed not to report Rishi's illegal activities, but her dark side has fans wondering what else she is hiding.
One fan tweeted that they think she will start killing off characters.
Looking forward to seeing who else she kills on the show.
They said: "I am quite glad they are giving @SarkerRebecca & @bhaskerpatel a storyline of their own and showing us Manpreet's devilicious intentions. #Emmerdale
"Looking forward to seeing who else she kills on the show. Especially knowing a few actors have decided to leave..."
A second said she could kill her own husband: "What will become of the lovely Doctor Cavanagh when Bernice leaves?
"An affair with Manpreet and they bump Rishi off?"
Another said on Digital Spy: "She's odd indeed low key shady. Don't trust her either. She could easily become a psycho Killer Doc."
