Three of the greatest detectives in the world--a renowned FBI agent turned private eye, a sculptor and lothario who speaks to the dead, and an eccentric profiler known as "the living Sherlock Holmes"-were heartsick over the growing tide of unsolved murders. Good friends and sometime rivals William Fleisher, Frank Bender, and Richard Walter decided one day over lunch that something had to be done, and pledged themselves to a grand quest for justice. The three men invited the greatest collection of forensic investigators ever assembled, drawn from five continents, to the Downtown Club in Philadelphia to begin an audacious quest: to bring the coldest killers in the world to an accounting. Named for the first modern detective, the Parisian eugène François Vidocq-the flamboyant Napoleonic real-life sleuth who inspired Sherlock Holmes-the Vidocq Society meets monthly in its secretive chambers to solve a cold murder over a gourmet lunch.
