Agent secret X-9

In 2003, Denoël launched a single-issue revival of Agent secret X-9, a classic newspaper comic strip character. This French edition collected the work of the strip's most celebrated creative team, offering a concise, standalone glimpse into the hardboiled espionage world of the mysterious X-9. While brief, the volume serves as a curated entry point for readers interested in a foundational piece of adventure-strip history.
