Any Stevenson fans idling about Edinburgh on Tuesday (13th) should get themselves down to the National Portrait Gallery between 10 and 5 when the whole of Treasure Island will be read aloud to celebrate the great man’s birthday. John Sessions and Nigel Planer are on between 3 and 4. I’m reading Chapter 31 at 4, and Chapter 33 at 4.24 – or at least that’s the plan: timings, needless to say, may slip.

So I may have to follow Sessions…
