THE FORUM - A World Of Ideas - presented by BRIDGET KENDALL.

British queen of crime fiction and global bestseller, PD JAMES, gives her own views on the abiding popularity of the detective mystery and suggests that the ordered and moral world it evokes is a great comfort to a world vexed by seemingly insoluble problems.

We look at the problem of famine with Irish economic historian CORMAC O'GRADA, who offers guarded optimism about our ability to eradicate major famine in the near future as long as we remain vigilant to its causes.

And taking us back two thousand years, Danish literary scholar KARIN SANDERS brings us face to face with the mummified corpses of ancient sacrifice and explores the stories they tell us and the ones we tell about them.
