It is very likely The Whistler was inspired by The Shadow, which began nearly a decade earlier. Like the Shadow, the Whistler seemed to enter and exit the criminal underworld without ever being seen. He would watch the evil doers carry out their schemes, yet they never saw him, even though he would tell us what they were thinking in their presence. His voice sounded equally sinister to The Shadow, too. It was was a slithering tenor, hissing the "s's" and often laughing "heh-heh-heh-hehheh!" at the foolishness of the guilty. Both series had similar opening lines: The Shadow "knew what evil lurked in the hearts of men", whereas The Whistler "knows many strange tales hidden in the hearts of men and women who have stepped into the shadows." When Bill Forman served 1/2 year in the military, Marvin Miller substituted as The Whistler.
