This month World Book Club comes from the Belgium capital Brussels for an Agatha Christie special.

The programme visits the Bibliotheca Wittockiana to discuss one of the bestselling crime novels of all time: Murder on the Orient Express by Agatha Christie in which that shrewdest of detectives Hercule Poirot hunts for a killer aboard one of the world’s most luxurious passenger trains.

To help untangle this fiendish puzzleknot and discuss the enduring popularity of the Queen of Crime are acclaimed crime novelist Sophie Hannah who has brought the renowned sleuth back to life again with her sequels, and James Prichard, great grandson of Agatha herself.
