This is a slow-moving but beguiling story of lost innocence. There's a subtlety and intelligence here rarely found in British costume dramas. The filmmakers go to enormous lengths to recreate Edwardian England, but never allow the period detail to stifle the storytelling. Although life with the Maudsleys seems idyllic--an endless round of picnics, cricket matches and parties--there is always an undercurrent of violence. The Maudsleys are inveterate snobs. The terrifying Mrs Maudsley (played by Margaret Leighton) simply can't countenance the idea that her daughter would have an affair with a man so far beneath her on the social scale as Burgess. The little boy carries the messages between the lovers without ever quite understanding how explosive their contents are. --Geoffrey Macnab
