Nick Carter Double Novel #2

"America's premier detective hero returns in two action-packed pulp thrillers! First, 'Whispers of Death' undermine the construction of a New York power plant, leading the Master Detective into one of his strangest cases! Then, a cryptic call for help from the Khan of Iraghan summons Nick Carter from his New York headquarters through a winding maze of murder leading to the Florida Everglades as he follows the deadly 'Trail of the Scorpion.' Plus, Nick Carter teams up with The Shadow in 'Calling Nick Carter,' a rare crossover from the Golden Age of Comics, and battles 'The Voice of Crime' in a lost radio adventure by Walter B. Gibson!"
