Patricia Carmichael is the character all Line Of Duty fans love to hate.

When it was announced that she would return for the sixth season, we just knew there were tough times for AC-12 ahead.

We don’t know what she’s really up to, why she called off surveillance on Operation Lighthouse or if she’s the fourth ‘H’ (although many fans have their theories).

But we do know this: she is one hell of a character who causes a big reaction whenever she appears on screen with that sarcastic grin and cool delivery of killer lines.
