Mafia 69. Curse of Blood.

Why both? Seriously, for his, as he says, "not the most powerful brain," that's a significant point. Because you won't immediately figure it out from the newspaper, but watching the roles – block + kill: the chance to kill a Knight of Justice, whom you otherwise wouldn't be able to defeat.

Actually, the flower is clear; there's only one other option, a bard, but it seems unlikely. It's more interesting why he's so sure that the Mafia killed the Sword Maiden. Well, logically, it's more beneficial for her to kill, but I personally find it difficult to understand that from the newspaper.
