ONE cannot imagine a more delightful guide to England than M. Andre Maurois , who has won the position of the official interpreter of England and the English to the French. As readers of The Radio Times will remember, his talk in the scries on ' Ourselves as Others See Us' gave a most delightful impression of this country and its customs as seen by a particularly intelligent foreigner fully conversant with English history and the English tongue. Many English listeners will envy M. Maurois ' family when they have heard his talk tonight.
