First, do no harm. But as New Orleans PI Micky Knight discovers, not every health care provider follows that dictum. She stumbles into a tangle of the true believers to the criminally callous, who use the suffering of others for their twisted ends. In a city slowly rebuilding after Katrina, one of the most devastated areas is health care, and the gaps in service are wide enough for the snake oil salesmen—and the snakes themselves—to crawl through.

The seventh Micky Knight mystery.
