Private Passions

Ruth Ozeki won the Women’s Prize for Fiction in 2022 with her novel The Book of Form and Emptiness. The judges called it a ’complete joy to read.’ She’s also a film-maker and a Zen Buddhist priest, and her books draw on her Japanese-American heritage. They also convey her deep concern for our environment, taking on topics such as industrial agriculture, ocean pollution and mass consumerism. Her most recent book, The Typing Lady and Other Fictions, is her first collection of short stories – and the Typing Lady of the title has more than a little in common with Ruth herself. Ruth Ozeki's music includes Albeniz, Praetorius, Prokofiev and Benny Goodman.

The botanist Dr Sandra Knapp is a senior researcher at the Natural History Museum - but that title doesn’t convey the sheer adventure of her work. She’s a kind of Indiana Jones of the plant world, travelling to remote regions of Central and Southern America and beyond. Her speciality is the Solanum genus, which includes potatoes, tomatoes and aubergines – and she has found and named more than a hundred new varieties. The rainforests, where she has worked for more than 40 years, are a long way from the dry rural deserts of New Mexico, where she was born. Her music choices include works by Mozart, Brahms, Hindemith and Holst, as well as music inspired by the biodata of some of her beloved plants. Presenter Michael Berkeley Producer Katy Hickman

Michael Berkeley's guest is actor and TV presenter Peter Purves. Purves has been involved in two of TV’s longest-running and best-loved institutions - he was one of the earliest companions to travel in the TARDIS with Doctor Who (1965-66), and for ten and a half years from 1967 to 1978, alongside John Noakes, Valerie Singleton and Leslie Judd, he presented Blue Peter – entertaining the nation’s children with demonstrations in everything from competitive swimming to scaling the Fourth Road Bridge. A dog lover, he has also presented TV coverage of dog show Crufts for many years. Purves's musical passions include Mozart, Tchaikovsky, Elgar and Sondheim, alongside tracks by Louis Armstrong and Count Basie - both of whom he remembers seeing perform live in concert.Presenter: Michael BerkeleyProducer: Graham Rogers

The best-selling writer Alison Weir knows precisely what sparked her interest in history: at the age of 14 she read what she calls a ‘really trashy novel’ about Katherine of Aragon – and a lifelong passion began.Since then she has written 38 books, selling more than three million copies around the world. Her non-fiction titles include biographies of Eleanor of Aquitaine, Isabella of France, Mary Queen of Scots and Elizabeth of York. She has also written many historical novels – including a book about each of Henry VIII’s six wives.In her most recent novel, The Cardinal, she focuses on the rise and fall of Thomas Wolsey, who enjoyed a prominent and powerful role in the court of Henry VIII.Alison's music choices include Bach, Beethoven, Ravel and Purcell.

The Canadian crime fiction writer Louise Penny has sold more than 18 million books around the world – and she was a late starter: she was 45 when her first book appeared, after working for two decades as a broadcaster and journalist. Success as a fiction writer came quickly: her first novel Still Life won numerous awards, and introduced Chief Inspector Armand Gamache, who works in rural Quebec. Louise has just published her 20th book featuring Gamache: in The Black Wolf, he’s taking on a powerful conspiracy attempting to make Canada the 51st state in a fight over natural resources.Louise's music includes works by Beethoven, Michael Nyman, Bach and Neil Young.Presenter Michael Berkeley Producer Clare Walker
