There is one lovely scene, though, set in the twinkly damp of the South Bank, when B tells Darcy he is "a pompous arse" who folds his underpants and then scampers, penguin-fashion in her too-tight evening frock, alone, to her flat. She treats him mean and, hey presto, he is at the door, begging to be let in. If only life were like that. If only this film had been like the book.
