Diana Winthrop and her mother arrive in Paris, where a World Exposition is taking place. Mrs. Winthrop had started to feel very tired during the journey, so after they check into their hotel, Diana calls for a doctor. After examining Mrs. Winthrop, the doctor sends Diana in his carriage to his own home, where his wife prepares a medication. A number of things seem odd to Diana, but things become much more worrisome when she returns to the hotel. The desk clerk does not remember her, her signature has disappeared from the hotel register, someone else is occupying her room, and her mother has completely disappeared. Written by Snow Leopard

Himself - Host: Tonight we are going to tell the story of a woman who disappears into thin air. By the way, have you noticed that thin air seems to be the type of air most conducive to disappearances? There, certainly, is a fact well worth knowing. Now, in case you seem to recognize parts of the story, don't be alarmed. It is familiar because it is a classic of its kind. Many, many people have borrowed this legend, quite profitably, too. Two novels have been written about it, and it has been made ...

Pat Hitchcock was a Pretty Decent Actress
3 October 2008 | by HitchcocSee all my reviews

A young woman and her mother arrive in Paris. They check into a hotel. The mother is quite ill and the doctor sends the young woman off to get some medicine. It's all a ruse. When she returns, her mother has disappeared. She begins her personal investigation into the missing mother's whereabouts. One must suspend belief when one considers why this whole persiflage takes place. When we finally find out what happened it makes no sense why these people couldn't have kept the daughter in the loop. She was certainly a cool head, rather staid, and wouldn't have presented a security risk. For a government to have gone to so much effort to cover something up is beyond belief. Also, to have done what they did in a couple hours is also ridiculous. Can you imagine how hard it would be to set all this up, including the remodeling of the hotel room? It's an interesting episode, but it's not the Twilight Zone, so things should have some verisimilitude.
