Who Knows What Evil Lurks In The Hearts Of Men?
The Shadow knows! The weed of crime bears bitter fruit, but none more deadly than the criminal genious called THE BLACK MASTER. Clearly, it’s a case for The Shadow… to uncover this emperor of evil who has turned New York into a city of fear!
Not since Sherlock Holmes locked wits with Professor Moriarty have there been such formidable opponents on the battlefield of crime! The Shadow, the elusive voice in the night whose mocking laughter haunts all who have ever heard it; the man of many faces who is all things to all people in the name of justice. And The Black master whose invisible hand kills the very men who serve him, leaving no trace, no quarter, not even an ounce of pity. Only terror… and a black metal tag which promises more to come.
