I write "apparently quotes" because, from Philip Hensher's review, it's clear that the novel is full of such statements:
Thirlwell's manner is full of phatic gestures, ones intended to announce an approaching weightiness that never quite arrives. "To begin again, at the beginning." "In my opinion that is enough." "This book is about…" (repeatedly). Over and over again we are told, by a writer perhaps too young to remember Anne Elk, that "I have a theory…"Yet, if it is classed as a novel, statements like these become problematic; one can attribute them to the narrator, yet not so readily to the author. In novels, the author cannot come right out and say anything without immediately having it taken away by the novel. This theory does not belong to me.
