The narrative assertion
"The Doctor's examination of the old book (beat_fb70834277ed4a04) leads to his discovery of the hidden note (beat_6d56cfd6b393164c), setting in motion his investigation into Castrovalva's fabricated history. This discovery is the catalyst for his suspicions about the town's recursive nature and the Master's involvement."
