Acquisition
In the CEO/CTO office of the Palisade Property Bank, there is a mechanical puzzle that can be solved to open a hidden area. When they are in the correct configuration, all the blocks will light up. To solve it, perform the actions of raise, turn, raise, turn, turn, raise. The dossier is located in a safe hidden behind a painting, inside the hidden area.

Or you can use the vents. There is an entrance behind the bigger TV in the CEO/CTO office. After a bit of crawling you can find the hidden room.

Use
The dossier serves as one piece of evidence that may be submitted to K to complete the mission.

If submitted to K, completing the mission by hacking the city's info hub will result in the dossier's photo being displayed in public. Additionally, the story "Flight 451: Picus vs the Truth" will appear in the Samizdat newspaper.
