Shadow Double Novel #55

"The Shadow crushes Supercrime in three action-packed adventures that inspired the classic 1940 Shadow movie serial. First, explorer Kent Allard is invited to join 'The Green Hoods,' a hooded secret society whose true purpose is an enigma. Then, airplanes carrying wealthy passengers disappear over the Rockies, setting The Shadow on the trail of the criminal mastermind called 'Silver Skull.' Lamont Cranston and Margo Lane seek to save the city from murderous terrorists in 'Prelude to Terror,' a 1939 radio classic. Plus, 'From Pulp Page to Silver Screen' featuring exclusive interviews with screen Shadow Victor Jory and Shadow stuntman George DeNormand."
