Experienced Forensic Expert

Exploration Stage: Station
From: Detective
Description: It says here that the secret organization's important information was spread by mobile phones. A mobile phone - what is that? In any case, if such a thing exists, it will be stored in that iron safe in the corner. It's locked, of course, but it's not a problem for such an experienced forensic expert like me. I just need a listening device to hear the clicks of the lock. Can you find it?
Completed: Here, I'll show you how to crack open a safe. You take the device, attach it to the door and turn the disk until you hear a click. Then you turn it in the opposite direction and continue like that until the safe is opened...
