Warning: contains major spoilers for Line of Duty series 1-6.
You could say we’ve taken this too far. You could be right. You could also say that, for a Line of Duty fan attempting to solve the Jo Davidson family mystery, it’s useful to know that Tommy Hunter was 13 years old when Jo Davidson was born, making him more likely to be her brother than her father. Or that John Corbett was born two months after Jo Davidson, making it impossible for his mother Anne-Marie McGillis to also be her mother.
And then there are the real questions, such as: the day before AC-12 raided Hillside Lane Station in series six, it was Kate Fleming’s 35th birthday. Did she bring in doughnuts? Had Kate come in worse for wear from one too many glasses of white in Frederico’s with Jo? The people demand to know.
Taken from police records glimpsed on screen and episode scripts, below are the key dates mentioned in Line of Duty, in chronological order, right from the start. We’ll update as series six continues. Use it to bolster your theories and beat your friends in arguments. Carry the fire, team.
