Reason for the Treason

If you ask me, the attack on our convoy is suspicious. I told Mistress Mihaela that there must be a traitor in the village, but she isn't concerned. It's understandable. She's got to worry about gathering a new tithe. I've taken it upon myself to figure this out and I could use your help. I'm making discreet inquiries but I can't be seen speaking with the help. That's where you come in. You can be my assistant sleuth.
