Мафия 25. Under The Jolly Roger!

He wrote that he bought off the murderer. I'm interested in his role. I don't see any clear hints about it, except for the invoice, which could identify him as the treasurer, but where are the clues then? But perhaps the invoice is a clue, and the evidence is its connection to the English army and the note about espionage.

Yes, the mafia could have blocked one of their own to divert suspicion from him.
