Reading for lighter moments, and a capable handling of a legendary theme. 1889, Paris, and a younger sister condescendingly squired by her bored, cynical older brother for three days at the Exposition. Dinner, a return to the hotel, her brother loans a young American 100 francs -- and then disappears. Next morning --a blacnk wall where his room had been, his name gone from the register, his existence completely denied. The frantic sister is helped by the chance reappearance of the young American, and a happy ending, romance, rounds out the entertainment.
