Мафия 39. Piece of emptiness for the small December.

I tried to find clues for the deck of cards using visual search—the first 200 images based on profile quotes yielded nothing, so the clue is most likely contained in the name or the text. Overall, I agree with the reasoning regarding the murders. As for the psychology, I can't say anything morni gave himself away, so I'd like to wait for one more newspaper.
