If you got the game through Jonathan's website as an extra for having purchased Dark Fall: Ghost Vigil there, you should have a walkthrough for The Displacement.
Here is what his blog says, talking about what you get when you purchase Dark Fall: Ghost Vigil from his site:
Point and click, keyboard and mouse.
Game 1: XXv: The Displacement
Game 2:Dark Fall - Ghost Vigil
Walkthroughs for both games.
Maybe have a look around? The walkthrough should be there somewhere. If you can't find it, let us know.
