The author of the journal introduces himself as an old man who has lived for years in an ancient house accompanied only by his sister, who serves as housekeeper, and his dog, Pepper. He has no contact with the local inhabitants, who say he is mad. The house is circular in form and its weird appearance includes peculiar decorations that suggest leaping flames. It has had an evil reputation for centuries and had been empty for many years when he purchased it. The diary will record his strange experiences and thoughts.
