Feet of Clay (Sunny Childs Mysteries)

Her personal life may be a mess. And no one said her family was sane. But as lead detective at Atlanta's Peachtree Investigations, hard-nosed, fast-talking PI Sunny Childs is always up for cracking a case.
And now starring in her sixth mystery, Sunny is in thick. When her cousin Lee-Lee, a documentary filmmaker who's interviewing convicted murderer and rapist Dale Weedlow, invites Sunny along for the ride, Sunny knows her very presence will probably convince her flighty cousin that the sicko's been framed. But Sunny ends up going, and to her surprise, things are, indeed, not as they seem.
Evidence of a cover-up looms behind the gentility of the local politics, business, and law enforcement, and as usual, Sunny finds herself deep into the original murder case. But with the locals closing their doors in her face and the time before the convict's execution running short, Sunny has to hurry if she's going to get to the bottom of the six-year-old murders of two girls whose feet had sunk deep into the Southern clay.
