This book is a horror-mystery novel by Arthur Leo Zagat, famed for his dime novels in this genre. At one moment the place was a gay, carefree city of pleasure-seekers; the next it became a dark metropolis of the damned, with a million men and women cowering from the clutches of the Little Men who sprang from their dank lairs, to pillage and murder at will. Somewhere, Roy Parker knew, was the girl he loved, held by the dread Master of Darkness whose mad designs brought tortured, bestial death to all who came within his power!
