Sam Leith’s guest on this week’s Spectator Book Club podcast is Joanna Pocock, talking about Greyhound (Fitzcarraldo Editions), in which she tells how America and American ways have changed in the time between two bus trips she took across the country, in 2006 and 2023. The Spectator also has a review of the book (“a road trip like no other, a personal memoir interwoven with history, anthropology and landscape”) by the novelist Lee Langley.
