I commend Cubachik!
So, what do we have?
We have a clue pointing to Red Chrisfield, as there's no mention of her device in the newspaper this time, and she's listed as having a sniper rifle.

As it turned out later, the sniper left a book called "The Code of the Perfect Warrior" in her lair, and a footprint with a strange cross was found in a dusty corner.

I don't think this is related to the "arrows marked with the sign of the elements and a fang" series. Clearly, one of the clues is a red herring; there's no doubt about it. I'm curious which one it is?

The observation about Neira is also good. If she's a serial killer, then I'm not infected! However, just like with Calypso, who spent all day yesterday advocating for the execution of suspected Berters and is now doing the same with no less zeal. In this case, my illness in the first night still makes sense and isn't just for show.

We have two options: investigate the new clue pointing to Red or try to execute Mana. I don't like either option.

On the other hand, the red herring should be related in some way to the killer's profile, right? Although, remembering the methods of the red herring enthusiast, Registr, it might be less likely than with Thorius.

I like the clue about Ryś, the bow, and Robin Hood, and I don't think it's far-fetched; it only has three links. In particular, the correlation with her quiet behavior; it's tough to be an unknowing mafia member in this harsh world where everyone wants you dead and can send you on a mission as a blind tool. Although, that's not a great argument – I, for example, spent the second half of the last game being a recluse. Moreover, if we're talking about behavior, I dislike Archie even more; he only posted one and a half messages throughout the game, and his faith gives him swords and strength in his heart.
This clue also reminds me of Perfect World, lol.

Regarding the cross: the religious theme, Delirious with her signature; Archie, who has become more active with his religious chants; Zybr with his god complex; and Rhubarb, according to yesterday's clue. However, yesterday's clue was about a serial killer, lol.
