Amateur criminal

Exploration Stage: Capuchin Movie Theater
From: Lewis Capuchin
Description: Naturally, I did not immediately understand what was happening. It was only when I noticed the smell of smoke that I finally understood what the murderer had done. The smoke was coming from the film in the projector, which had been replaced in a messy way. It almost caught fire, but we were able to extinguish it with liquid nitrogen from a container. Look for it.
Completed: Liquid nitrogen is ideal for extinguishing a film that is on fire. The fact that the film in the projector cannot even be changed properly means that the culprit is someone who is not familiar with film equipment. Perhaps it is a rival film vendor plotting to ruin the premiere screening.
