Thank you, Tilly2. I have just listened with rapt attention to the Book of the Week reading of episode 1 on Radio 4 on iPlayer. It is on at 9.45am every day this week till Friday. The 15 minute programmes are repeated at night at 12.30am. According to your amazon link, the book will be available in hardcover on 27th August for £8.96, though I have just accessed amazon directly and it gives 4th July as the release date.
