I suspect I'm an NPC in a horror novel.
Every ten days, unfamiliar guests arrive at the manor where I live, bringing no gifts for their hosts. Before long, they begin disappearing one after another, until not a single one of them is left.
Once they've all vanished, the manor falls silent for a few days. Then the skeletal carriage comes rolling in from the distance with another batch of guests, and the cycle begins again.
Until one day, a guest cornered me against a wall.
"I know you," the guest said with conviction. "I'll get you out of here."
