Deception in Savannah — C.L.R. Dougherty

Connie Barrera is ready to move on.  She's the business partner and mistress of a married doctor who runs a weight loss clinic, but she wants out.  He's not willing to buy her shares, so she resorts to extortion.  The doctor has recently killed a pedestrian in a hit-and-run accident to which the only witness other than Connie is a street hustler with attention deficit disorder and a photographic memory.

Connie threatens to disclose the doctor's role in the accident, jeopardizing the thriving clinic. Unbeknownst to Connie, their major investor is the local drug kingpin who is confused by the antics of Connie and her alcohol-addled lawyer.  The mobster decides that his empire is under attack by an unknown rival.  His lethal attempts to eliminate the threat are frustrated by chance and the incompetence of his subordinates.

The police finally find the somewhat puzzled eyewitness who eventually recalls his clear but misplaced memory of the accident, and everyone's plans begin to unravel.

Deception in Savannah is a character-driven novel set in the colorful old city of Savannah, Georgia.  The author lends a native's perspective on the city and its people to this tale of humor and intrigue.
