My guest on this week’s Book Club podcast is Mark Bostridge. In his new book In Pursuit of Love: The Search for Victor Hugo’s Daughter, Mark describes his quest to uncover the traces of Adele Hugo and the doomed love affair which cost her her sanity. He tells me how Adele’s story chimed in poignant ways with his own life and what it taught him about the unstable emotional contract between biographer and subject.
