Author-Book Relation

The Author-Book Relation is how J.S.Frost and Robin Higham are related in a way. In most of the books, Frost talks as though he is Robin, and in the second book he is him. This means that J.S.Frost is a fictional character on his own and his relation to Robin is being the same person with different names. It isn't surprising, to say that Frost knows about Durtris when only the ` elite ' are.
