Synopsis by Hal Erickson
Le Secret du Docteur is a Gallic rendition of The Doctor's Secret, a play by James M. Barrie. Marcelle Chantal plays Lilian Garner, the bored, disenchanted wife of Richard Garner (Leon Bary). Preparing to run off to parts unknown with her lover Jean Colman (Jean Bradin), Lilian is prevented from doing so when Jean is killed in a motor accident, right before her eyes. The attending physician at the scene of the tragedy is Dr. Brady (Maxaudian), Garner's best friend. Brady is aware that Lilian and Jean were lovers, but he intends to remain mum when invited for a weekend party at the Garland's home. The method by which the truth is revealed is at once clever and cruel but in complete accordance with the mood of the rest of the story. This adaptation of The Doctor's Secret is the French version of the 1929 English-language talkie, which starred Ruth Chatterton as the errant wife and Robert Edeson as the discreet physician.
