"Accidental" Arson

It's no use trying to get Andrei to tell us who he's working with. He won't talk, and we can't risk alerting his accomplice. We need to get rid of him, and it needs to look like an accident. Once Andrei's been dealt with, set fire to his rug and let the whole estate burn down. Andrei isn't someone you want coming into power. He's as ruthless as he is cruel.
