It is arguably the greatest tale of child abduction ever told: the story of the Pied Piper of Hamelin has been part of German folklore for centuries. But who was the colourful figure who led first, the plague of rats and then the children, away forever from the town of Hamelin? Michael Rosen takes a Journey through the medieval streets of Hamelin via rat-infested London, ancient German pagan ritual, and the whispering silence of Eton College library. He finally uncovers the truth behind the legend that should never again be thought of as just a fairy tale. Producer Lizz Pearson
