In true Line of Duty fandom style, a number of eagle-eyed fans have noticed a significant detail about the most recent glimpse of the character - and we can't help but think they're onto something.

One person summed it up on Twitter: "Mother. Of. God. Roll neck jumper under jacket, hair tied back in a low bun, slight build but very fierce, I'm sure she reminds me of someone..."
A second person added: "Love her. Also this polo neck and blazer is a very strong motif this series. What does it mean?", which prompted a third to connect the dots, asking: "Is she Jo's sister??"
A fourth echoed this, picking up on DI Kate Fleming's love of a polo-neck. writing: "Aah Patricia is back and she's rocking a Kate polo neck... think I'm going to have to invest in one."

On the announcement of her reprisal, Anna herself gave a mention of her new look. She said in a statement: "Pat's back, I can't remember what she's doing there, nor would I be allowed to blab, but suffice to say she's got some new clobber and she's ready to bust some balls."

Viewers last saw Patricia Carmichael in series five when AC-3 was brought in to investigate Superintendent Ted Hastings as a potential member of a ring of corrupt police officers colluding with the OCG and a contender for a mysterious 'H'. It's safe to say when she's in the room, she means business!
