In the books, Karen is unfashionable and odd, and doesn't really mind what she looks like because her main focus is her job.
That is why Lauren worked closely with costume designer Lesley Abernethy to make her look humble but cool at the same time.
To get into character, she also explained how she got to understand the plot and the case like a detective.
She said: "I read the scripts hundreds of times.

"Like a detective, I got huge pieces of paper that I taped together and put on my wall, with details of the whole case.
'It's so complicated that I had to make sure I understood it, so I kept referencing back to this map on my wall.
"There are so many suspects and I had to walk into each scene remembering if Karen really did suspect them or if she secretly trusted them.'
Lauren appeared in
She has played Marshall in Outlander since 2017.

The Sex Education star is back again.
Portraying DC Jason Murray, Chris explained how his character brings humour to the show and how his relationship with Karen evolves through the episodes.
He said: "Jason is really well-intentioned and good-natured, but just doesn't quite get things right a lot of the time.
"He's desperately trying to hit the mark, but he just misses it.
"He's maybe not the brightest detective on the team, but he kind of makes up for it in his hard work and through his relationship with Karen - they develop into a really good team and she helps him find his stride.
"That relationship builds through the series - at first, they don't really see eye to eye and she's quite frustrated that she's been given such a potentially useless member of the team!
"But he really shows his qualities as they move on and eventually he comes into his own, and really stands up for himself in the later episodes."
Chris explained Jason to be a sort of mummy's boy who loves working out in the gym and enjoys doing basic things in life too such as going out and dating.
