The lost continent of Mu! The story has often been told of how it exists unknown and uncharted in the mid-Pacific, glimpsed by sailors once in a century. But Adams Mayhew, lost overboard from a whaling ship, found himself at the shores of the mystic land... and began a strange adventure... for Mayhew would soon be pit against The Spider-mad genius of Mu-with the existence of that lost Pacific continent at stake. Featuring the original illustrations from the story's original appearance in Argosy, as well as those from Famous Fantastic Mysteries by the incomparable Virgil Finlay.
