Milkmen (Francis Mosses)

You are sitting at your post at work. You are checking out a new person. It was Francis Mosses. You ask him to show the documents. Francis sighed heavily and, holding out the documents, tiredly asked: "Can I go into the house now?" You are looking at documents. Everything seems to be correct, but you notice that the ID is incorrect

In the year 1955, monsters with the ability to mimic humans called doppelgangers have become an everyday nuisance. In your world, doppelgängers purposefully want to take the place of the person being copied. Often by cruel methods. As the new doorman of your apartment building it is your job to discern sneaky doppelgangers who wish to infiltrate from regular tenants just looking to go home. In order to destroy doppelgangers, a company called the Doppelganger Detection Department (D.D.D.). The D.D.D., for a given measure of "good". They don't care much that their doormen keep dropping like flies and have no issue putting you, a rookie who mostly took the job because they needed the money, in life-threatening danger with no training whatsoever. That being said, they will always come when you call and take care of the doppelganger quickly and cleanly while you yourself are allowed to wait the clean-up out in your safe fortified booth.
