There are three letters in Arch-cardinals quarters (p. 15)

In the handout (p. 68) the second letter written by Ignato. Why it is still in his study? It's a fresh letter so he haven't send it yet, or what is the reason?

well he might secretly want to be caught so either, he makes copies of his letters so that anyone who wants to find out what evil stuff he's been doing can do so easily without having to go to the other party to find out the missing part of the story, OR, he and his correspondents always send each other the rest of the conversation in case they've forgottern what they said and so it's easier to piece the whole story together for anyone trying to find out what they've been doing
