In today's programme Claire Armitstead talks architecture, international crime and bad science with Dan Cruickshank, Misha Glenny and Ben Goldacre.
Misha Glenny is in Hay with McMafia: Crime Without Frontiers, which took him to many of the world's most dangerous regions, ranging from the drug-trafficking jungle settlements of Colombia's cocaine barons to the unknown cities of a rural China that have grown rich on the profits of counterfeiting and people-trafiicking.
The architectural writer and broadcaster Dan Cruickshank has also traveled to remote, sometimes treacherous parts of the world in researching his BBC series, Dan Cruickshank's Adventures in Architecture. He explains why a giant rock carving of Buddha qualifies as architecture, describes some of the wonders he has seen on his travels, and names the building he would most like to save.
Ben Goldacre, the Guardian's Bad Science columnist, lays into quacks the world over. But while he is down on alternative therapists and particularly homeopaths he explains why the placebo effect cannot be dismissed out of hand.
We also hear from Joanna Trollope about why she got on down with the clubbers, and became one of Chelsea FC's staunchest fans. Plus the comedian Catherine Tate tells us why she is greatly bovvered about Shakespeare, and which of her characters she would cast as Juliet. We end with music from the novelist and singer Wesley Stace.
