In a special Christmas edition of the roadshow, we look back over some of the most memorable, valuable and moving items to have appeared recently and ask: what happened next? Jewellery specialist Joanna Hardy delves into the mystery of a beautiful, jewelled brooch in the shape of a ballerina, believed to be the work of the renowned firm Van Cleef & Arpels. Could the archives of the Parisian jeweller hold the key to the secret - and unlock a value of £50,000? Geoffrey Munn reveals the reasons why he became the custodian of a tiara that he first encountered on the show 30 years ago, while a set of Dutch silver spoons is revealed to have a hidden meaning in support of the wartime resistance movement. Fiona welcomes guests and familiar roadshow faces to Anglesey Abbey in Cambridgeshire, richly decorated for Christmas. Pictures expert Frances Christie joins Fiona to explore the ways artists have used a surprising range of colours to depict snow, while Joanna Hardy reveals the history behind a perennial favourite Christmas gift - the charm bracelet. Food historian Ivan Day uses his culinary expertise and antique equipment to create an elaborate twelfth cake, a festive favourite that dates back to medieval times. A story of wartime heroism and sacrifice unfolds when the family of a man awarded the Albert Medal, Arturo Fanconi, attend a service of remembrance in his honour and meet a long-lost friend.
