Beholder 2

On roughly your 3rd day of the game, a Stranger will appear in the lines (one screen right of your 1st floor work area) with whom you can interact. Talking to him will give you the task of finding Window 101. Ask Nicholas Page (the courier) about Window 101, which will make footsteps appear that you can track. Follow these to the left and click on them to continue down the hallway instead of going further into Ferguson’s office, earning you the trophy.
