This quest can be acquired from the Rattay Bailiff. Speak with him about where you can learn to read. He will suggest that you visit the scribe in Uzhitz. The scribe is usually in the same house as the bailiff, which can now be seen marked on the map. When you find the scribe you will have to pay 50 Groschen for your lessons.
Once the cut scene ends, you will have to read the book on the table and take note of what it contains. After reading it go back to the scribe and when he asks you what the book contained, choose the following dialogue option:
– That being greedy doesn’t pay.
Next he will ask you to read the book in Latin, which can be found propped up to the right of the English one. Read it and return to the scribe. When he asks you what the book contained, choose the middle option as shown in the image below.
