The Quiet Game by Greg Iles

Natchez, Mississippi. Jewel of the South. City of old money and older sins. And childhood home of Houston prosecutor Penn Cage. 

In the aftermath of a personal tragedy, this is where Penn has returned for solitude. This is where he hopes to find peace. What he discovers instead is his own family trapped in a mystery buried for thirty years but never forgotten—the town’s darkest secret, now set to trap and destroy Penn as well.
