In this edition, Mary visits Powderham Castle in Devon, to spend time with the Earl and Countess of Devon and their two young children. Known as Charlie and AJ, the newest generation of one of Britain's oldest families are taking up the challenge of running a great stately home, reinventing the castle and the Earldom for the 21st century. Mary's time with the family reveals stories of romance and tragedy, as she discovers the attics and secret passages of this extraordinary home. In the historic kitchen she bakes a Devon cream tea and is shown a Powderham classic - curried cockles. She is also inspired to make a delicate peach posset for a Midsummer Eve woodland party the family are throwing to celebrate their two year anniversary at the castle, as well as to thank the local community.
