Masters of Darkness

A beam of darkness had been paid on Fifth Avenue for precisely fifteen minutes, and a forewarned underworld had reaped the harvest. Every source of valuables that could be found had been cleaned put. An amazing and baffling new weapon of the Underworld put New York at Crime's mercy, and has left the city's police blindly grasping for answers. Written by noted Science Fiction author Murray Leinster, "The Darkness on Fifth Avenue" and its three sequels are finally collected in book form.
