Mafia 97. Land of Colored Dreams Auto-translated

She was just looking at some cute animal-shaped pendants – a bear, an owl, something with big ears – when a low growl made her turn around…

Could it be this?

I don't see any evidence pointing to a serial killer.

Same here, colleague.

a bear, an owl, someone with big ears

A rabbit? Yes, that looks like a clue!

Looks like a company from Winnie-the-Pooh.

No, it looks more like this: http://www.thefoxandthefeatherband.com/

What is that strange smell? Heavy, rotten… Hmm… Swamp sludge, dried spiders, mouse tails, frog skin, bat wings… Swan feathers and a goose beak?..

I can’t figure out if this is a clue related to the mafia or not…

Maybe. I guess I mistook what I wanted to happen (Arandor's death instead of Mirko's) for reality.

Execute Arandor

I can't figure out if this is a clue pointing to the Mafia or not...

This hints that the Sorceress killed without leaving any clues.

Cop, are you Mafia?

Ney is a hunter. The snowman is a unicorn, put to sleep and killed by a witch. Everything is quite bad.

Okay, let's say we have this chain:
Winnie the Pooh -- Milne -- "Ivan's Day (June 24)" -- Ivan Tsarevich -- Shaman

Thank you for protecting Naire and the bear. It's a shame that no one was provoked...

Cop, are you a mafia member?

I'm a Heroes of Might and Magic fan.

I made a deal with Nebk, but he’s still going to execute me. That’s why you can’t trust anyone after something like that.

Lol.
