In the morning, workmen pulled up the floor between rooms 12 and 14. Under the floor they found a box. There were old papers inside the box. Anderson thought that the papers belonged to Nicolas Francken - the man who had disappeared in 1560.No one was able to read the writing on the papers. It was in a strange language. The writing was brown. The ink looked old. But Anderson did not think it was ink. He thought the papers were written in blood!
