Third Brick

A strange phone call at three o'clock in the morning ruined my peaceful life. "Under the third floor tile, there's something you shouldn't forget." Even the agent only showed me the rental house I lived in in a hurry. Who would have known, the third brick counted from the door? The more I thought about it, the more frightened I became, and I reached out to pick at the edge of the tile. Just then, the lights went out. In the darkness, I heard a very light sound coming from under the floor. It turns out that I have never lived alone.
