It is the turn of the century and, having survived the struggle with Sherlock Holmes at the Reichenbach Falls, Professor James Moriarty is alive and well and about to realize his plans to establish crime syndicates in the major cities of the United States. But suddenly he is called back to London, where his vast criminal society has been overrun by a rival concern led by the shadowy Sir Jordan Jack Idell or Idle Jack a supposed gentleman hoodlum acting on behalf of criminal elements in France, Italy, Spain, and Germany.
As Moriarty fights back against both the unruly crime families and the forces of law and order readers are thrown in among the lurkers, punishers, dippers, cracksmen, and the professor s elite guard.
Moriarty lives again and revolts against those who attempt to oust him from his rightful place as king of "Napoleon of Crime."
