Digging for ancient Native American artifacts, an archaeologist finds murder instead.
Louisiana's past is as layered as an onion, with American, French, and Spanish history all resting atop the myriad tribes who have spent millennia on the Mississippi. Alan Graham knows how to peel back the layers. A contract archaeologist in Baton Rouge, he scrapes out a living one dig at a time. Hired by a wealthy landowner to search his property for a cache of long-lost Tunica Indian relics, he expects to find only dirt. But when the client is murdered for his curiosity, Alan knows he is close to the discovery of a lifetime.
To find the artifacts and sniff out the murderer, he must work alongside his competition: the overeducated Yankee Pepper Courtney. As the two dig into the dead man's past, they find it may be safer to leave some things buried.
