Scientist and world-saving explorer Doctor Ardan was created in 1928 by French author Guy d'Armen in the pages of the magazine L'Intrépide five years before Doc Savage.

In The Hurricane Master (1931), Doc Ardan is asked to investigate mysterious hurricanes that disturb maritime traffic in the French Pacific. He is able to expose and defeat the science pirate Krakatax, the master of Hurricane Island, and rescue the daughter of American billionaire William Dorgan, with the help of an operative from the Continental Detective Agency and flying ace Phineas Pinkham.

In The Secret of Frigidopolis (1933), Doc Ardan receives a mysterious inheritance from a long-lost uncle and goes looking for a futuristic city hidden in the icy wastes of Patagonia.

These two new ground-breaking SF adventures in this popular French series have been translated and adapted by Michael Shreve.
