The Nyctalope Steps In is a collection of 15 stories featuring France's premier pulp superhero from the 1920s and 1930s. The title piece is a translation of a rare tale serialized in a regional newspaper in 1942, the last story ever written by the character's creator, Jean de La Hire, in which his hero comes to terms with France's occupation by the Nazis. Fourteen other stories, eight of which were especially written for this volume, offer more exciting adventures from the Nyctalope's secret origins, lost in the mists of time, to his excursions into the future, from the blood-drenched trenches of World War I to the far-off planet Mars. Also included in this book is a complete Nyctalope chronology by Emmanuel Gorlier.
