Mafia 44. Time of Troubles

Considering that the city could easily blockade another city, such an execution is not the best idea.

Naver Leengard - checks the innkeeper
Arandor - protects Ivan
Spear - blocks the princess
Neyra Drake - blocks the blacksmith
WisTrit - checks the monk
WishmasteR - protects the drunkard

I agree with everything here. But Tox is unclear. Here's what I'm not sure about - who was killed, although the version with the fake prince seems more plausible. As for who did the killing, I would add an angel to the crusader and werewolf: he is also in armor in the picture. But again, the werewolf seems like the most plausible option. In fact, there are many options for who the killer is: all those not involved in the newspaper.

It seems to me that the clue is this, and the iron man is a synonym for "man in armor" to avoid repetition.
