The Kirkus review is pretty much on the mark. Jance can be an excellent writer, and Brady's a great character, but the feeling one gets from this book is that Jance had to meet a deadline and just cranked another one out. "Don't forget to throw in the serial killer, and focus on the macabre and grisly aspects of the killings and burials. Throw in some local color, move the townfolk along."
Jance starts a number of plot lines that go nowhere, as Kirkus explains. She focuses on the .50 caliber rifle, when the shootings could have been done by any rifle. She repeatedly raises the specter of a missing armory, which goes nowhere. There's no explanation of why a killer with several large rifles needs to borrow a deer rifle, or why the killer chooses to flee the area right as Brady discovers his identity.
Hopefully in future books Jance will avoid the cliches the Brady series is falling into, particularly the unnecessary detailing of the killing process.
