Tales of Humanoid Creatures

Mia comes home and finds someone in the house who looks exactly like her husband Gavin. A message arrives from Gavin with the rules. The things take the shape of people, they swallow a person and take the memories along with the face, and fire is the only thing that kills them. She cannot get out of the building. Her parents arrive for a visit. Her father wants his meat raw and his memories of the family do not line up, so Mia settles it: he is one of them. She tells him they are going out to the countryside to pray, drives him there, and burns him. At home again she watches her mother and sees the same signs. There are figures hidden in the wall paintings. The Gavin beside her is a copy as well, and when she puts it to him he uses his hold over time on her. She runs to a hospital, where the doctors and the patients are copies too. The real Gavin reaches her there and stops time long enough to tell her that the things are turning up all over the world and that the spread is being reported as a new virus.
