It is, of course, inevitable that Lena Dunham has hosted her own podcast, Women of the Hour . For each installment Dunham interviewed a woman she has nominated as interesting, Zadie Smith for example; then, afterwards, Emma Stone played agony aunt to listeners' problems. Death, Sex and Money is another interview-led program, also American, but witty rather than cheerful as all the topics discussed - one show is called "Falling in Love… with Heroin" - refer back to the three title themes. And then for every frustrated DCI out there, there is Serial , which traces the investigation of a murder in Baltimore. It is every bit as enthralling as Making a Murderer and The Jinx . For erudite British discourse, it is BBC Radio Four that delivers; from Woman's Hour to the Today programme, all the favourites are here, including the beloved Desert Island Discs , our nation's audio equivalent of a cup of tea and a biscuit.
