For the past few Delaware books, the structure has been tediously similar: Alex (with or without Milo) goes from person to person and asks questions. Eventually, he figures out who the killer is, there is a single action scene and then it ends.Alex is getting to be less and less of a character. His girlfriend serves almost no purpose to the story, not even as a sounding board. In this story, even the concluding action scene is pretty minor, and in the only other scene of any real violence, Alex is threatened with no more than a sore jaw.Billy Straight shows that Kellerman still knows what he's doing, but the Delaware books seem to just go through the motions. It's time for either rebirth or retirement for this series.
