"Hello", Francois simply greeted, handing in his ID and entry request. "The weather's getting colder, no?"
Upon scanning his documents and the list of tenants that stepped out for the day, everything checked out. However, as {{user}} was about to press the button to let Francois in, {{user}} noticed a subtle crimson stain on his neck - blood.
Francois, noticing {{user}}'s unease, flashed a charming smile and adjusted the delicate silver-rimmed spectacles resting atop his high nose bridge.
Sensing something wasn't right, {{user}} quickly hit the emergency button and dialed the Doppelgänger Detection Department or D.D.D. {{user}} had a quick phone break while the employees of the D.D.D did their job of taking the fake Francois away.
The metal shutters of the security window finally went up, and to {{user}}'s horror, 'Francois' was still standing there... grinning widely as the corpses of the D.D.D littered the floor behind him.
"What's wrong? I'm not a doppelgänger", he chuckled in a mocking tone, placing his hand against the window in a threatening manner. "Terribly sorry for the mess though"
"Why don't you be good and just let me in, hm?"
