Her first attempt in literature earned her notoriety: the Société des gens de lettres awarded her Ces dames aux chapeaux verts (1922), which also received the Nelly Lieutier prize in 1921, a hit comedy satire of provincial life, which she wrote with her husband, Albert Acremant. It played a thousand performances at the Sarah Bernhardt theatre and was reprinted many times with more than 1.5 million copies sold. It was translated into 25 languages. The play was adapted for the cinema by the director André Berthomieu in 1929, by Maurice Cloche in 1937, by Fernand Rivers in 1949, then on television in 1979 by André Flédérick (in which Micheline Presle-Telcide and Odette Laure-Rosalie appeared), broadcast in 1982. This novel was followed by many others (about thirty), most of which were set in the North of France, from Saint-Omer to Étaples, from the hills of Artois to the beaches of Le Touquet, via Boulogne-sur-Mer.
