The Monachkosville Mystery
The rooms are all locked, surprisingly. However, the doors still creak as you push on them, wood threatening to tear like paper if you place too much force on it. You try every door, pressing your ear when you notice an inkling of life through a curtain. You don't hear much more than TV static in one of the rooms, though. Nothing of note. Perhaps whoever's in there fell asleep while watching the nightly news. If there even is a local TV station around here. You decide your best chance to get into any of these rooms is to look around for an employee.
Maybe you just need to look around for a minute longer.
