The Antiques Roadshow makes a return visit to Bowood House in Wiltshire where treasures include an 18th century box engraved with a secret code, an enamel cigarette case by a Russian master craftsman and a collection of items from the golden age of tailoring. Jon Baddeley is intrigued by a mysterious 18th century box engraved with a secret code that may once have contained cosmetic 'beauty spots' while books specialist Clive Farahar enjoys a cartoon inspired by a news report about a lion that escaped from a circus and took refuge in a Wiltshire school. The team admire a collection of vintage transistor radios, a scent bottle housed in a wagon drawn by a pair of goats and a blue enamel cigarette case presented to an Englishman who aided the White Russian cause during the Russian Revolution. Mark Hill meets two young men with a passion for tailoring and the work of Montague Burton, while glass specialist Andy McConnell is inspired by the story of an ordinary Stourbridge glass engraver, as told by a proud son. In a moving encounter, Fiona Bruce meets a man who only discovered he had a different biological father when he found letters to his late mother from an American soldier, prompting him to undertake a remarkable search for answers in North Carolina.
