"Who knows what evil lurks in the hearts of men? The Shadow knows!" From 1930-1954, the wealthy Lamont Cranston was one of the best-known characters on radio, using his mystical powers to fight crime. The only person who knew The Shadow's true identity was his "friend and companion, the lovely Margot Lane". Through the years, The Shadow was portrayed by Frank Readick, Orson Welles, Bill Johnstone, Bret Morrison, and others. As listeners were reminded at the end of every episode, "The weed of crime bears bitter fruit. Crime does not pay! The Shadow knows!"
"As one of the basic prototypes of what has come to be called Pop Art, the Shadow is unique and irreplaceable, a legend in his own time. A classic character who looms slouch hat and shoulders above all others of his kind, he is an inevitable as a guilty conscience, an unseen power that awakens within all of us our most deep-rooted fears of mortal retribution. There has never been a force quite like him." (Jim Harmon, The Great Radio Heroes)
A very bad guy fills light bulbs full of explosive gas, witch goes off every time the lights are turned on. Then he spreads them around the city and blackmails the city. He then he robs the city during the blackout, the Shadow stops them and the bad guys scheme blows up in the bad guys face. Crime doesn't pay.
Any additional comments?
The poisonous gas, of which there is only one glass bottle in the entire world, is put into light bulbs which are installed around the city. When the switch is turned on an explosion happens.
