The Master of Darkness demonstrates that "crime does not pay" in three pulp thrillers by Walter B. Gibson writing as "Maxwell Grant."

First, disappearing fish and vanishing corpses provide a sinister puzzle that only The Shadow can solve! Then, death threatens the life of an eccentric scientist when his amazing invention attracts the attention of a "Syndicate of Death." Finally, murder lurks behind Mardi Gras' satanic cosplay as The Shadow grapples with a criminal mastermind concealed by "The Mask of Mephisto."

This instant collector's item showcases the original color pulp covers by Modest Stein, the classic interior illustrations by Paul Orban, and supporting commentary by pulp historian Will Murray.
