The Shadow battles incredible super-villains in startling pulp thrillers by Walter B. Gibson and Theodore Tinsley. First, the Knight of Darkness hunts down a mysterious super-foe who appears only as a kaleidoscopic blur and has kidnapped Margo Lane! Then, "Blue Face" conducts a  series of sadistic attacks that net miniscule proceeds, but only The Shadow knows that there is far more to the bizarre crime wave than meets the eye. Plus, a lost Shadow adventure from Radio's Golden Age!
