Three live in one house: a vampire, a werewolf, and a ghost. The vampire tries not to feed on people, but he doesn't really manage to avoid it. The werewolf is terribly tormented by what he becomes during the full moon, and each time he tries to arrange things so that no one gets hurt. The ghost is a somewhat strange and temperamental creature who keeps the house tidy, makes tea, and can even be seen by some people.
