Anna Mitchel has been writing letters to her French penfriend, Alexandre Tourville, for fifteen years, but hasn't seen him since an exchange trip when they were at school. When Alex, now a successful photographer, comes to work in London, Anna offers to put him up, but is astounded that the small, geeky boy she remembers is now tall, broad-shouldered and gorgeous, and has just broken up with his long-term girlfriend. Anna's female friends are soon swooning over Alex's Gallic charm, and Anna's boyfriend Nick is soon extremely jealous of her friendship with an attractive single man. Then Alex has to return to Paris to oversee the hanging of his photographs in an exhibition, and invites Anna to accompany him so that he can show her the city he adores
