Gaston Leroux (1868–1927) was a French journalist and author of detective fiction. In the world of French literature, he is best known for his tales of adventure and intrigue, which often feature audacious protagonists and complex, mysterious plots. Born in Paris, Leroux began his career as a court reporter and theater critic, which informed his richly descriptive writing and appreciation for drama. His days in journalism nurtured the painstaking attention to detail that would later be a hallmark of his literary compositions. Perhaps, his most enduring creation is the character of Joseph Rouletabille, a young journalist who becomes an amateur detective in the acclaimed novels 'The Mystery of the Yellow Room' (1907) and 'The Secret of the Night' (1913). These books stand out as pioneering works in the locked-room mystery subgenre and have been lauded for their ingeniously plotted puzzles which influenced generations of writers in the mystery and detective genre. Leroux's most famous work 'The Phantom of the Opera' (1910) is a riveting tale of love and horror that has spawned countless adaptations. His literary style is characterized by a blend of fantastical elements with a methodical, journalistic approach to storytelling. This scholarly narrative approach was reflective of Leroux's broader writing oeuvre, which spanned multiple genres but often returned to themes of the unexplained and the supernatural.
