The Knight of Darkness combats supercrime in an extra-length volume showcasing tales by each of the pulp wordsmiths who wrote as "Maxwell Grant." First, in a violent thriller by Theodore Tinsley, The Shadow investigates the murderous machinations of "The Prince of Evil," a sadistic fiend who delights in torture and human misery. Then, The Shadow enters a series of diabolical deathtraps disguised as a "Messenger of Death" to retrieve a secret formula in a classic mystery by Walter Gibson. Finally, Lamont Cranston tracks down a hidden serial killer in Bruce Elliott's "Room 1313." This extra-length collector's special showcases the original color covers by Graves Gladney and Modest Stein and the original interior illustrations by Edd Cartier and Paul Orban, with historical articles by Will Murray and Rick Lai.
