If Kurzen knows Thorsen's secret, then we have a spy in our midst. We must determine how the secret was leaked!
Thorsen's contact within Kurzen's camp was Bookie Herod. Herod is Kurzen's logistics officer and knows everything about the running of Kurzen's Compound. If you can get Herod's notes or records, maybe we can find out how Thorsen was discovered.
When we were still with Kurzen, Bookie's office was on the top floor of the camp's only two-story house. His records are probably still there.
These are Bookie Herod's notes and records.
Among them are: a list of supplies within the camp, material requests from Colonel Kurzen, and various letters and correspondences.
