Easy Innocence (Georgia Davis Mysteries)

When pretty, smart Sara Long is found bludgeoned to death, it's easy to blame the man with the bat. But Georgia Davis -- former cop and newly-minted PI -- is hired to look into the incident at the behest of the accused's sister, and what she finds hints at a much different, much darker answer. It seems the privileged, preppy schoolgirls on Chicago's North Shore have learned just how much their innocence is worth to hot-under-the-collar businessmen. But while these girls can pay for Prada pricetags, they don't realize that their new business venture may end up costing them more than they can afford.
