Crucial Recording

Exploration Stage: Lamplighter's Workshop
From: Mr. Black
Description: I want to figure out what happened on the night of the theft and who is to blame. But an empty tape recorder only confirms Carlos Light's guilt. Why did he hide the tape? The box is full of reels. It'll take time to find the right one. Your help wouldn't hurt.
Completed: The date on this reel coincides with the date the lamp crystals were stolen. So this is the one! We need to listen to the recording and write down everything we hear.
