old time radio show - my WWII father (miss him every time I see a video of him with my kids) probably enjoyed listening
Lamont Cranston - played a figure never seen, only heard
Who knows what evil lies in the hearts of men? was the refrain...
He was an invincible crime fighter * with special gifts which enabled him to overcome any enemy (*Steve Lavin?)
(I think the Shadow was referring to enemy as Syracuse, Villanova, G'town - I leave out UConn because back in the heyday of the Shadow, UNone was a nothing sports college)
all the best
