LINE Of Duty star Martin Compston has revealed fans are “pretty close” to cracking who the shadowy ‘H’ is.
The 36-year-old, who plays DI Steve Arnott in the hit drama, was speaking ahead of the epic finale on Sunday.
Appearing on The Jonathan Ross Show he admitted: “All these wild theories… some are pretty close!”
Martin appears on the ITV show on Saturday night alongside Line Of Duty co-star Vicky McClure.
She said they won’t even tell their parents the drama’s big twists.
The Kate Fleming actress explained: “It’s more your family and close friends who are like, ‘So are you going to tell me?’
“Even my mum – I was in their garden, dad went inside – my mum was like, ‘Come on.’ I said, ‘No, no!’ I don’t want to ruin it for them.
“I’d tell her, she wouldn’t tell anyone, but it’s ruining it for her then.”
Martin added: “Every year you worry, are we still relevant? Are people still going to be invested?
“Now we’re bigger than ever, getting new fans… it’s an intense period when it’s on.”
The Jonathan Ross Show is on Saturday 1 May at 9.35pm on ITV and the ITV Hub
