I don't know why I liked this better than the first volume in the series, especially as they're essentially the same story. Well, this one's shorter. That might do it. Although, that shorter length may result from this volume being absolutely pared down to essentials, with a laser focus on its subject. Blue, a private investigator, is hired to surveil Black, in what is perhaps the most boring watch-job in history. Black's a writer, and his day pretty much consists of spending his hours at home, writing at his desk, with the occasional exciting trip to the grocery story. Blue's understandably bored out of his mind, and his coping strategy is to become absolutely obsessed with the minutiae of Black's life, no matter how much this obsession with another man's life torpedoes his own.

The entertaining thing about this, and by far the most interesting part of it, is how the reader's made into just another watcher, albeit one as focused on Blue as Blue is on Black. It's a sort of nesting doll of obsessive gaze, and the book's just short enough that this reflected experience is a compelling one.
