The Murder Store — Dan Ames

Money buys everything...even murder. When the young daughter of a powerful Senator is kidnapped from a shopping mall in Iowa, her father calls in his old friend, retired FBI profiler Wallace Mack. Soon, Mack begins to uncover a frightening prospect: an online marketplace where wealthy psychopaths can buy their next victim. It's a race against time as Mack fights to save a young girl's life by putting The Murder Store...out of business.
