EMMERDALE fans have ‘worked out’ a harrowing twist concerning John Sugden after spotting ‘clues’.

John – played by actor Oliver Farnworth – first arrived in the ITV soap last year.

The former soldier has met half-sister Victoria (Isabelle Hodgins) and formed a relationship with Aaron Dingle (Danny Miller).

Viewers have been suspicious of John’s intentions for a while, sharing their thoughts online.

They already believe he has something to do with the mysterious body found in the lake.

Fans ‘rumbled’ the body was former villager Nate Robinson, who left last year – after spotting a huge hint.

The arm of the body in the lake was wearing a bracelet identical to one that Nate’s daughter Frankie made him.

Eagle-eyed viewers are convinced John murdered Nate after seeing a very similar-looking tarpaulin used when he disposed of Anthony Fox’s (Nicholas Day) body.

Believing Aaron killed the predator, John ending up helping in covering up the crime.

It was actually Ruby, Anthony’s daughter – whom he had abused – who killed her evil father.

One wrote:  “Okay anyone thinking John had something to do with Nate? That tarp wrapping has got me thinking. Might have to go back and watch to see if I can spot the connection.”

Another added: “It was John he’s not who he says he is and is a serial killer.”

The latest theory, however, suggests a tragic storyline ahead for John and Aaron’s relationship.

A viewer highlighted a “controlling” side to secretive John’s personality – sharing fears for Aaron.
