Agente Secreto X-9

A seven-issue Portuguese series from Edições 70, Agente Secreto X-9 (1981–1987) collects classic newspaper strips of the hard-boiled detective and secret agent, originally created by Dashiell Hammett and Alex Raymond. While the series spans the 1980s, it preserves the gritty, shadowy espionage of the character's 1930s origins. This Portuguese-language edition is notable for making these foundational adventure strips accessible to a new generation of European readers.
