It's hard to know where to begin with this ultra-weird story. It has a deceptively simple plot line involving a tragic arson in which scores of people are killed, but it morphs quickly into multiple story lines that revolve around two main characters: an accountant who sees something involving three school boys in the ruins of the afore-mentioned arson fire, and a schoolteacher in whose class the three school boys attend school. Reading this novel though for me was a bit like watching the film Mulholland Drive, in which there are at least two narrative lines--one real, one dream-like--but it's not clear until the film is over which is which, as though the movie was designed not to be understood upon a first viewing, but would need to be watched twice at least, perhaps several times in order to be understood. This novel is like that, but you would first have to care enough about the action and the characters to want to do so, and I have to say that for me, that hasn't happened. The biggest mysteries for me and the ones for which resolution is at best hinted at is who is the little mute girl, Sarah, and what is the significance of the train ride to the supposed sanitarium? Perhaps other readers have ideas. I can understand why this crafty book was shortlisted for the Giller Prize, but in the end I found it too artful and too horrible to justify more than one reading.
