In The Electric Mist With Confederate Dead

Description for IN THE ELECTRIC MIST WITH CONFEDERATE DEAD by James Lee Burke:

Hollywood has sent its emissaries to New Iberia Parish to film a Civil War epic in the steaming mists of the Louisiana bayou -- reawakening the ghosts of a past best left undisturbed.

The restless specters wait in the shadows for cajun cop Dave Robicheaux -- as he hunts a serial butcher who is preying on the less-then-innocent young. For these spirits are the guardians of Robicheaux's darkest torments -- and they hold the key to his ultimate salvation...or a final, fatal downfall.

This is #6 in Dave Robicheaux series.
