In The Nyctalope on Mars (1911), Leo faces the megalomaniacal Oxus, master of the secret society of the Fifteen, who is plotting to conquer Earth from his secret base on Mars.
Leo Saint-Clair, alias the Nyctalope, was created in 1911 by Jean de La Hire, one of France's most prolific writer of adventure serials.
Also included in this book is a complete Nyctalope chronology by Emmanuel Gorlier.
Sixteen other stories, all written especially for this volume, offer more exciting adventures spanning over a century, from Leo's first exploits against dark mystic powers in 1900 Paris, his adventures as an explorer in darkest Africa ...
His adventures, which spanned 30 years, created a template that was later adopted by other pulp and comic-book heroes, and continue today in new stories, of which this is the most recent.
Written in 1933, this is the origin story of the greatest of all French pulp heroes. Created by prolific writer de La Hire, it is presented here with three additional short stories also featuring the Nyctalope.
