World Radio

Robert Glenister is reading Ian McEwan's new novel, 'Saturday' by this week on Radio 4's Book at Bedtime. It's a day in the life story (cf. Ulysses) of surgeon Henry Perowne - comfortable and happy with his London life until he suddenly has to face danger. Here's the moment when, about to be beaten up by Baxter's henchmen, he suddenly notices the unmistakable twitching of Huntington's Chorea.
