Mafia 21.

The killer was very meticulous, so Aziral was left lying in his bed with his arms folded across his chest, one hand on top of the other. A crumpled piece of paper with a drawing of a tree lay next to his bed.
As yesterday, Morning went to the hospital with a severe head injury.
A mark from a large blade remained on the chest of the murdered WhiteLizard, and in the morning, when he was found, music from wind instruments could be heard outside the window. On his desk was an inkwell, a quill, and a piece of paper with a list of people and comments about each of them.
Someone was watching Neyra from a distance, careful not to attract attention.

Notes:
Manic, kill Pandora!

Morning is deliberately calming the townspeople so that they relax and stop thinking. Town, use your brains! Signed: one of you
