"The Prince of Evil"

"Stop frowning, my friend. You look positively sad! One would almost think you had lost your best friend!" - Benedict Stark 

And so begins Theodore Tinsley's answer to Gibson's Shiwan Khan saga.  "The Prince of Evil" is the first of four adventures, all in 1940, that documents the epic battles of The Shadow versus Benedict Stark, aka The Prince of Evil.  Yeah, you don't want to miss this run: "The Prince of Evil" from April 15, 1940, "Murder Genius" from July 1, 1940, "The Man Who Died Twice" from September 15, 1940 and finally "The Devil's Paymaster" from November 15, 1940.
