Silver Streak

George Caldwell travels from Los Angeles to Chicago for his sister's wedding aboard a train called the Silver Streak. On board, George meets a vitamin salesman named Bob Sweet and a woman named Hilly Burns. Hilly works for Professor Schreiner, a well-known but reclusive art historian who is on a publicity tour for his new book on Rembrandt. Devereau is a criminal who passes himself off as an art expert, and Whiney, Reace, and Johnson work for him.
