"Who knows what evil lurks in the hearts of men? The Shadow knows! The Master of Darkness investigates criminal conspiracies in two classic pulp thrillers by Walter B. Gibson writing as "Maxwell Grant." First, The Shadow follows a bloody trail of extortion and murder that leads from the back alleys of Paris to the country homes of New England to confront "The Blackmail Ring" in a 1932 thriller, the earliest never-reprinted adventure of the Dark Avenger. Then, a bizarre series of Philadelphia murders sets Kent Allard on the trail of another "finger" of the deadly criminal organization called the Hand. This instant collector's item showcases both of George Rozen's color pulp covers and all the original interior illustrations, with commentary by pulp historian Will Murray.
