“Blue Nude,” by Jonathan M. Bryant introduces us to Brad Sharpe, who has problems. Not just the problems you would expect resulting from traumatic injury and a destructive divorce. His ex-wife has gone missing and a priceless Picasso has been stolen. The cops have pegged Brad as a person of interest in both cases. Worse, a violent sociopath might want Brad dead. Only with the help of friends and his knowledge of the Georgia Lowcountry can Brad fight to clear his name and resolve the case of the Blue Nude.
