Ok i was reading your walkthrough you wrote out and i got up to the bit in the first part where i'm sophie and she has to find the UV light. you write; Now you'll be Sophie and you'll have to creep towards the entrance way
to get the UV light from the Crime Investigators box. Just crouch and
sneak past the first two guards and in the next room grab the pole on the
ground and sneak up behind the third guard staring into the box and club
him quietly to the floor; yet in my game she's in a gallery with the dead body and like 4 or 5 guards who she can talk to and she doesn't have to sneak around behind they talk to her, there's a box but it's locked. are we playing the same game? your walkthrough doesn't match this part of my game
