I'm not sure what I think about The Manual of Detection. It really is a very descriptive book - I have no problems picturing the world that Jedediah Berry is building. But, I just don't get the mystery. It's very subtle; in fact, I didn't really understand exactly what the mystery was until very late in the novel. Perhaps the point of the novel was to just to describe Berry's world. If this is the case, the book succeeded admirably.
