The Wheel Spins

Ethel Lina White is a master of psychological detective fiction, one of the favorite authors of film director Alfred Hitchcock. The novel "The Wheel Goes Round" was repeatedly filmed under the title "The Lady Vanishes". There is a commotion on a train that is rushing at full speed: passenger Mrs. Froy has disappeared without a trace. Will anyone believe her compartment neighbor, who claims that she was not traveling alone? Why did no one notice the mysterious disappearance? Is it a conspiracy, has someone gone crazy, or has there been a murder?
