Who is the "Recording Angel" in the novel, What’s Bred in the Bone?

At the beginning of the novel, mention is made of the Recording Angel. He is described as a bookkeeper, an Angel of Mercy and the Master of Muses. He has a staff, and one of his staff members is the Angel of Biography, The Lesser Zadkiel, who plays an important role in the telling of this story. The Lesser Zadkiel and the Daimon Maimus continually interject their conversation through the movie-like review of Francis' life. The Recording Angel does not actually appear in the book, but Davies mentions The Recording Angel so that readers can understand who The Lesser Zadkiel is and what he does. This concept of other-worldly beings supports both the structure and style of the story as well as the theme of beyond the physical realm.
