Fans of Line of Duty have spotted a grammatical error on a notice on the wall – and they believe it could solve a mystery.
The poster appeared during last night’s episode involving Acting Detective Superintendent Jo Davidson.
The sign read: “Please return all files once your finished with them Thank you!!!!” – Many viewers believe the misuse of ‘your’ could be a clue.
What do you think?
Hope AC-12 are investigated by the Grammar police next week #LineofDuty pic.twitter.com/PSgblvssrd

Wasn’t there a message sent to Jo Davidson on the laptop with grammar like this?
