The Devil Went Down to Austin by Rick Riordan

A slightly less entertaining Tres Navarre Mystery (Book 4) but still enjoyable. PW: Tres has taken a short term teaching job at the University of Texas at Austin. He is living with his brother Garrett, a computer wizard, and enjoying this easy assignment. But when Garrett’s business partner is murdered, Tres must switch from professor to detective. As Tres delves into Garrett's bizarre world to find the truth behind the murder, he comes face-to-face with the damaged relationships, violent lives, and billion-dollar schemes of a brave new high-tech world. Among the players: a corporate takeover artist with a trail of broken enemies in his wake and an overzealous desire to make Garrett's company his own; the victim's wife, a hard-edged beauty haunted by three generations of family failure; and the head of an oil-rich clan with more power than morals and enough skeletons in the closet to man a ghost ship. Connecting them all - the beautiful waters of Lake Travis and an unspeakable evil that lies within its depths.
