In "The Ring of Thoth," an Egyptologist visits the Louvre and accidentally witnesses a strange event.
Based on the short story by Sir Arthur Conan Doyle, Escape's adaptation is an interesting one with an unexpected ending. "The Ring of Thoth" was first published in 1890 and the short story is available online at Wikisource.
Mr. John Vansittart Smith, a British student of Egyptology, has come to the Egyptian Room of the Louvre to study. There he meets a curious looking attendant but otherwise, he is alone in the great hall. Not long afterwards, the quiet surroundings and his inability to concentrate cause him to drift off to sleep.
When Smith wakes, it is the middle of the night and he is locked inside the darkened museum. Soon, he becomes aware that someone else is there, too. A mysterious figure holding a light has come into the hall and opened the case of one of the mummies. Smith realizes that it is the attendant that he saw earlier in the day, and as he watches from the shadows, he becomes involved in the extraordinary story of the ring of Thoth.
"The Ring of Thoth" was adapted for Escape by Les Crutchfield and produced/directed by William N. Robson. Jack Webb, Thomas Freebairn-Smith, and Joan Banks starred. This episode aired on August 11, 1947.
