Letter to Caleb Menge is a document in The Witcher 3: Wild Hunt and is found only during the main quest, Count Reuven's Treasure, if Caleb Menge is asked about the treasure. Otherwise, it won't appear as Caleb will burn it prior to checking in on Triss.
Journal entry Edit
- Caleb, I have new instructions regarding the organization of the next execution. When you are ready to meet, place your Holy Tome in the drop box located in the column of the Eternal Fire altar in the southwest corner of the Bits. We will meet at the usual spot. Do not tell anyone where you are going and bring no one with you. Burn this letter after reading.
