Amazon.com's review of "Letter From an Unknown Woman": "By the time you read this letter, I may be dead," reads aging bon vivant Louis Jourdan from a letter found in his tiny hotel room. With tousled hair and a tux tired from yet another night of meaningless flirtation, he's startled by these opening lines and suspends his preparations to flee a duel in order to read the history of a love affair that he can't remember. For the rest of the film we're transported to the life of Joan Fontaine's awkward young Viennese woman, who has been hopelessly enthralled by the dashing pianist ever since adolescence. For a moment she was his lover, the emotional pinnacle of her life but for the philandering rogue simply another fling in a blur of women passing through his bedroom.
