El Misterio de Don Quijote

When Cervantes wrote El Quijote in 1605, the manuscript was sent to a printing press here, in Madrid. When the workers were about to lay out the book, they realized that the text shifted from chapter 42 to chapter 44. They assumed that it was a mistake that Cervantes made, so to fix it, they combined two paragraphs into chapter 43.

You have 60 minutes to find chapter 43 and escape the room.
