Introduced by Robert Robinson Graham Greene
In his new novel, The Human Factor, GRAHAM GREENE turns once again to the world of the Secret Service. The SIF is usually the subject of a thriller. But here Graham Greene makes it the background to a novel about the private world of a double agent who lives in Berkhamsted, the market town in Hertfordshire where Greene himself spent his childhood.
Graham Greene - heard though unseen - talks about Berkhamsted and why he has used it as a setting for his new novel.

Workshop: Elijah introduced by Owain Arwel Hughes with Benjamin Luxon (baritone)
Mendelssohn's much-loved oratorio has such powerful dramatic qualities that it prompted a contemporary writer to wonder why he never wrote an opera.
In the first of two programmes with combined Welsh Choirs, OWAIN ARWEL HUGHES tells the story of the writing of the oratorio, and rehearses for tomorrow night's performance, demonstrating the skill with which Mendelssohn achieves his effects in what is surely some of his finest music.
