John Sandford - The Devil's Code

Three stars. Solid and enjoyable.

A hacker acquaintance of Kidd's is killed under suspicious circumstances, and his sister asks Kidd to investigate. He pokes around, and finds the signs of a bigger mystery, with threads leading to another murder, the NSA, and a mysterious hacker group called "Firewall". The story sprawls a bit, and the plot isn't as tight as the first two Kidd books--too much of the action seems to be going on in places other than the main narrative. And there are only a few instances where Kidd's character gets stretched beyond a thumbnail sketch, which is a shame.
