Radio: Pick of the Day

JOHN PEEL on Home Truths last week was obsessing on the subject of Internet relationships, as though virtual romances were a recent phenomenon. He should tune into the Afternoon Play (2.15pm R4). Michael Butt's Contemplating Adultery is based on the steamy five-year correspondence between Sarah Austin, a married Victorian translator, and a German prince. They never met but shared wild intimacies. Penelope Wilton lends a wistful restraint to Sarah's suggestiveness while Bill Nighy opts for breathy overload.

Another unexpected delight: Jane Austen's Lady Susan (7.45pm R4) stars Harriet Walter as the unscrupulous young widow and Maggie Steed as her cold-hearted confidante.
