The subject of this literary suspense really interests me: surveillance in our modern times, how everything we do can be tracked, and how far is too far when it interrupts an ordinary person's life. 
 I hesitate to call this a suspense because it moved too slowly, but like I said, the subject matter really grips me. The protagonist is an Ivy League professor who is being tracked and threatened and the readers figures things out along with him. It builds pretty well but then the end was a let-down. 
 There were some references to cinema and philosophy that I didn't get, but I appreciate that the voice of the protagonist was spot on, very analytical. When he speaks of being in love it seems very dispassionate, but I accept that this is realistically how he would speak/think, so I'll get passion from another book.
