The Whistler was one of radio's most popular
mystery dramas, with a 13-year run from May 16, 1942 until September 22, 1955.
If it now seems to have been influenced explicitly by The Shadow, The
Whistler was no less popular or credible with its listeners, the writing
was first class for its genre, and it added a slightly macabre element of humor
that sometimes went missing in The Shadow's longer-lived crime stories.
