EASTENDERS fans are convinced Denise Fox has sussed Gray Atkin’s evil ways after a tell-tail clue - but did you spot it?
The evil lawyer is currently in hospital after Kheerat Panesar hit him over the head with a vodka bottle.
The pair got into a fight after Kheerat confronted him about his murderous ways.
As viewers will know, Gray has killed his late wife Chantelle Atkins, Tina Carter and Kush Kazemi since he moved to the Square three years ago.
Over the past few months, Kheerat and Whitney Dean have been trying to expose him for his crimes.
On Tuesday, the businessman finally got the serial killer to admit what he has done, but it ended in Gray on the floor lying in a pool of his own blood.
Gray's wife Chelsea returned him to find Gray unconscious on the floor with Kheerat looking over him.
The beautician called an ambulance and told the call handler that it was Kheerat who had hurt him - which left viewers fuming considering she knows about how evil Gray is because of Kheerat and Whitney.

While Kheerat made a quick escape, Gray was rushed to hospital.
During tonight's instalment, Chelsea's mum Denise started to question why Kheerat had done such a thing.
"I just don't understand why he would do something like this," she said to her daughter.
Chelsea looked extremely sheepish considering she knows Gray's past.
When Denise asked her what Gray had done to deserve being attacked, Chelsea snapped back: "I said I don't know mum."
Denise then pointed out the bandage on Chelsea's hand, which is covering an injury that Gray gave her.
Denise asked: "Still sore?" The beautician replied: "It's fine."
"All them years wearing heels and you go and fall over in the shower," Denise said.
Fans of the show think that Denise may have realised what Gray is capable of...
One wrote on Twitter: "Ah I think Denise might clock on soon."
A second said: "Denise is getting suspicious!"
