Marcel Achard (1899–1974) was a French playwright and screenwriter whose popular sentimental comedies maintained his position as a highly-recognizable name in his country's theatrical and literary circles for five decades.
In 1937, the World Film News journal carried a brief news item about Hitchcock's intention to adapt an Achard short story:
Other newspaper reports from October named the project as False Witness.
However, shortly afterwards, the studio offered Hitchcock the existing Lost Lady project, which he accepted. This was released the following year as The Lady Vanishes (1938).
