Is Carmichael H? The clues in Line of Duty episode 6

*Major spoilers in this video for Line of Duty*

Line of Duty viewers are increasingly suspicious of Anna Maxwell Martin’s cartoonishly smug Detective Chief Superintendent Patricia Carmichael, who has taken over AC-12 as Superintendent Ted Hastings (Adrian Dunbar) faces enforced retirement.
