Minimal observers

Exploration Stage: Negotiation Room
From: Mr. Black
Description: The former believer fears the vengeance of the shadow cult and says he would do anything if the Security Service would guarantee his safety. But there is no guarantee that he won't run away the moment he gets what he wants. So I'm going to sew a button with a tracking device into his coat. I'll install it as soon as I can, so bring me the button!
Completed: Be careful not to drop the button. It's a minuscule tracking device that the inventors at the Sheriff's Department have been working on all night. Now all you have to do is quietly attach this to your ex-believer's coat. They'll never know it's there!
