Toby Jones and Holliday Grainger star in a new BBC Radio 4 full-cast dramatisation of Dodie Smith's enduringly popular coming-of-age novel. In the 1930s, seventeen-year-old Cassandra Mortmain lives in a crumbling ruin of a castle in the Suffolk countryside. Her father, an author wrestling with writer's block, spends his time reading detective stories; her bohemian stepmother Topaz is an artist's model, and her beautiful older sister Rose is determined to escape the poverty of their existence - ideally by marriage to a rich man. Intelligent and observant, Cassandra chronicles the eccentricities of her relations in her journal, in a bid to capture her family and their lives at the castle. When two rich American brothers, Simon and Neil Cotton, arrive unexpectedly, the family's isolation is disrupted. Rose accepts a marriage proposal from Simon, and as she is whisked off to a world of wealth in London, Cassandra is left to deal with the increasingly bizarre behaviour of her father - as well as her own feelings for Simon. .. Dodie Smith's charming, funny and poignant love story is a classic of 20th-Century English literature and this sparkling adaptation, starring Toby Jones and Holliday Grainger, will enchant and delight.
