Hester takes up judo, and proves better at it than at Trivial Pursuit. She also takes her Chinese vase to TV's 'Antiques Road Show', where it is valued at £6,000. Concerned about having such a valuable item in the house, the Fields surprise a burglar and Hester's judo skills overpower him. They engage the burglar in playing Trivial Pursuit until the police arrive. 

After Sonia suspects husband John of infidelity with his secretary, Hester has her own suspicions about William when he comes home reeking of perfume - after having a business meeting with perfume saleswoman Miss Henshaw who was merely trying out some samples on him. After this is cleared up, the Fields go to a dinner-dance and draw deserved admiration for their energetic Charleston.
