Eagle-eyed Line of Duty fans spot huge clue in kitchen linking H to Steph Corbett

An eagle-eyed Line of Duty viewer horrified fans after pointing out a major clue linking 'H' to either Steve Arnott or Steph - John Corbett's wife.

Tonight, Steve was clearly unhappy with Steph after discovering that she had told Superintendent Ted Hastings about his dependency on painkillers.

After Steve was delivered a clear non-verbal warning, he went straight over to Steph to confront her about it.

While Steph apologised, she insisted that she was just looking out for him. He later returned and they enjoyed a night cosying up together.

But despite romance appearing to blossom between them, once Steph had left her house Steve's suspicions got the better of him and he began searching her home.

After a thorough look around, he found £50,000 in notes in her attic - presumably given to her by Hastings.

But fans were distracted after noticing the letter 'H' on her kitchen tiles.

Viewers flocked to Twitter to speculate, with one sharing a screen grab of the tiled H and writing: "There’s a H on the tiles!!!! #LineOfDuty."

While another commented: "Could be massively overthinking this, but.... Have we found H #LineOfDuty."

A third wrote: "Me seeing the ‘H’ in the kitchen tile pattern #LineOfDuty."

"My sister has sent me this. It is now my new theory Steph is indeed H and is so proud of her manipulation she displays it in her kitchen. #LineOfDuty," another suggested.

So is it a clue? Or just another red herring?
