Monster

You threw a party at your country house. The house was large, two floors plus a basement and an attic, but even so there were a lot of people, everyone huddled together like canned sardines. You went outside to breathe and suddenly, out of the corner of your eye, you noticed some red figure, but turning they didn’t see anyone. Thinking that were imagination, you returned home, but there was no one inside, only drink cups were scattered around the house.
