The Master of Darkness teams with G-Man Vic Marquette in two never-reprinted pulp novels by Walter B. Gibson. First, an enigmatic message from a dying man leads The Shadow to uncover the strange secret behind "The Ghost Murders." Then, the Master of Darkness attempts to prevent "Ships of Doom" from being destroyed by a hostile foreign power! This collectors special showcases the classic color covers by Graves Gladney and George Rozen and also features the original interior illustrations by Tom Lovell and Edd Cartier and historical commentary by Will Murray.
