RENEE MONTAGNE, HOST:
Good morning. I'm Renee Montagne. A town in Germany once had a legendary rat problem. Hamelin was the setting for the tale of the Pied Piper, who lured its rats into a river, and then led away its children when he wasn't paid. Some 700 years later, the rats have returned and chewed through the electric cable powering the town's fountain. Could be a job for another Pied Piper, or tourists could just stop scattering bread crumbs for birds near the fountain. It's MORNING EDITION. Transcript provided by NPR, Copyright NPR.
