Andy Broussard, the plump and proud New Orleans medical examiner, obviously loves food. Less apparent to the casual observer is his hatred of murderers. Together with his gorgeous sidekick, psychologist Kit Franklyn, the two make a powerful, although improbable, mystery-solving duo. Among the dead collected in the Big Easy floodwaters after Hurricane Katrina are three nude female bodies, all caught in the same brush tangle, none with water in their lungs. Broussard knows in his ample gut that this was not an act of God, and not the work of Katrina. But Broussard has perhaps the biggest challenge of his colorful career.
The city and all its records are destroyed, practically the entire population is scattered, the police force has no offices, and many of the rank and file (who haven't defected) are homeless. Soon, Broussard and his sidekick are on a dangerous journey through the obscenely damaged city, leading them to a kind of evil that neither of them could imagine.
