Steranko paintings graced the covers of this Shadow massmarket paperback series that ran for 23 volumes between 1974 and 1978. Steranko's classic portrait of the Shadow graces the back cover.

From the back cover:

WHO KNOWS WHAT EVIL LURKS IN THE HEARTS OF MEN?

The marks of death were upon them. A mysterious round burn no bigger than a dime scarred each forehead; upon each throat was a thin, almost invisible white line. The police were baffled, but each of the victims knew that his time was up and his page in the book of death had come due. It was obviously a case for THE SHADOW but the most famous crimefighter of all was missing!

Where was the Master of Darkness? Had he finally succumbed to his brilliant adversary, the High Priest of the Cult of Kali? The evil genius who had infiltrated New York's underworld like a disease was now determined to destroy the last obstacle in his mad lunge for total THE SHADOW!
